Hello, I'm Laura Lynch.

Good evening. I'm C. David Johnson.

This is As It Happens.

Tonight:

Spewing invective. The oil leak in the Kalamazoo River stretches twice as far as it did yesterday -- and Michigan residents are outraged.

Dead reckoning. A morgue on the Arizona border long since ran out of room for the corpses of illegal immigrants -- but more keep coming in.

Assault on Battery. If St. John's City Council gets its way, the last wooden wharf in the city's Outer Battery area will be demolished.

Developing story. Ansel Adams' grandson says a widely-publicized bunch of negatives were not taken by his grandfather.

Sure, they're wallowing -- but not in self-pity. A British scientist does the grunt work -- and discovers that well-cared-for pigs are capable of optimism.

And...nothing dentured, nothing gained. There was probably blood, sweat and tears when a dental technician made Winston Churchill's false teeth -- a set of which has now been auctioned off for thousands.

As It Happens, the Thursday edition. Radio that's sure the teeth are close -- but no cigar.

It's deja vu all over again.

No sooner had we stopped getting bad news about the oil spill in the Gulf of Mexico than we started getting bad news about an oil leak in Michigan. When we went to air yesterday, the slick in the Kalamazoo River stretched twenty-five kilometres long. Today, it has more than doubled in length.

Late last night, the Environmental Protection Agency, or EPA, took over the clean-up from Enbridge, the Canadian company responsible for the leak. The EPA now estimates that nearly four million litres of crude oil have leaked into Michigan's waterways.

Mike Nofs is a state senator in Michigan. Yesterday, he pushed through a resolution to co-ordinate the clean-up effort. We reached Senator Nofs in Ceresco, Michigan, near the spill site..

And the bad news continues for Enbridge. At their offices in Vancouver, Greenpeace is protesting the company's application for the Northern Gateway pipeline, which would run from the oilsands in Alberta to Kitimat, B.C. Oil tankers would then take that oil from B.C. to Asia.

The pipeline application is currently under review by the National Energy Board and the Canadian Environmental Assessment Agency.

And Greenpeace isn't the only group with concerns. Karen Campbell is Staff Counsel with Pembina Institute. We reached her at her office in Vancouver.

For generations, fisherman Jack Well's family has been using a wooden wharf situated in the picturesque "Battery" enclave of St. John's, Newfoundland. It's not as sturdy as concrete -- but whenever a storm hits, or the extremities of the winter damage the structure, Jack and other local residents step in to patch it up. It's a popular and well-established part of the area's local heritage, having stood in the harbour for nigh on two hundred years.

But now the last wooden wharf in St. John's is under threat from St. John's city council, which wants it demolished.

Chris Brookes is the chairman of the Outer Battery Neighbourhood Association. We reached him in St. John's, Newfoundland.

That, of course, was Sir Winston Churchill's rousing "fight them on the beaches" speech from 1940. And it's clear from his stirring words that Mr. Churchill wasn't afraid of baring his teeth -- even if they were false.

The British Prime Minister wore dentures throughout the Second World War -- dentures specially designed to maintin the stentorian quality of his voice. And today, a pair of those customized gold and platinum false teeth was sold at an auction for more than twenty-three thousand dollars.

Nigel Cudlipp put those dentures up for auction. He's the son of the dental technician who made Winston Churchill's false teeth. We reached him at his home in Ockley, England.

That's the jaw-dropping conclusion of the first part of tonight's program. And we'll give you more to chew on right after the news. When we return:

An Arizona morgue's nightmarish dilemma. One border facility is over-capacity with the bodies of people who died crossing illegally from Mexico.

Snap decision. Matthew Adams doubts those negatives a California man picked up at a garage sale have nothing to do with his grandfather Ansel.

Hog on the high. Research proves that pigs are capable of feeling hopeful -- provided they're not housed in the equivalent of a condo with no furniture.

Stay tuned. I'm LL.

And I'm DJ.

Arizona's governor is promising to appeal a judge's decision to block key parts of the state's new immigration laws -- laws that would give greater powers to police, in order to target illegal immigrants.

The legal fight comes at a time when the number of people caught trying to cross the border has actually fallen in each of the past five years.

That's got Bruce Parks feeling a little confused. He's the Chief Medical Examiner for Pima County, a part of Arizona that shares the border with Mexico. And his morgue -- which is already over-capacity -- is expecting a record year in 2010. In this month alone, he's already seen fifty-nine bodies come through his front door -- all of them believed to be illegal immigrants.

We reached Bruce Parks at the morgue in Pima County, Arizona.

Are they the garage-sale find of the century -- or are they as worthless as that scratched ABBA forty-five you bought for a quarter from your neighbour two doors down?

Last night, collector Rick Norsigian told us about some photo negatives he bought for forty-five dollars at a garage sale. He believes they're the work of Ansel Adams -- and that they may be worth as much as two hundred million dollars.

Matthew Adams does not agree. He's the grandson of Ansel Adams. And he says the negatives are not his grandfather's work. We reached him at the Ansel Adams Gallery in Yosemite National Park, California.

When it comes to grilled cheese sandwiches, some are as subtle as extra mild cheddar, and others are as in-your-face as a blob of past-its-best-before-date gorgonzola.

Last night, we told you about the owner of Bread Butter Cheese, who operates an illegal, covert grilled cheese sandwich shop out of his Manhattan apartment.

Talkback, on the other hand, gets much more up in your grill about this North American dinner staple.

The expression "pearls before swine" is meant to suggest a wasted effort. I mean, why would pigs have any appreciation for pearls? They would just look at them and oink, and then try to eat them, before deciding that the jaw-breaking round things were infinitely less valuable than, say, a handful of potato peelings. You think hogs see beauty or joy in the world? In a pig's eye they do.

Except that, sometimes, they do. It all depends on where they live and how they're treated.

Dr. Catherine Douglas and her team from Newcastle University's School of Agriculture have shown that pigs are capable of hope and hopelessness. We reached Dr. Douglas at home in Newcastle, England.

We all know there are infinite variations on what can be considered good. But who knew there were so many shades of bad?

Well, Talkback, it turns out.

A few nights ago, we told you about a would-be singer named Emma Amelia Pearl Czikai. She was a contestant on "Britain's Got Talent", and she was off-key enough that her singing drew some biting criticism from the show's chief snarkster, Simon Cowell. She was also sensitive enough to then sue Mr. Cowell for being mean.

Hearing Emma sing prompted Talkback to compare her to the late Florence Foster Jenkins, who made a career out of being a boldly -- and, it seems, unwittingly -- awful songbird.

Well, tonight, Talkback is adding yet another voice to this off-key musical medley.
