Former Republican vice-presidential nominee Sarah Palin is seen Tuesday on The Tonight Show with Jay LenoFormer Republican vice-presidential nominee Sarah Palin is seen Tuesday on The Tonight Show with Jay Leno (Paul Drinkwater/NBC/Associated Press) Former Republican vice-presidential nominee Sarah Palin turned into a standup comic on Jay Leno's Tonight Show, dropping one-liners about the White House, Congress and Tina Fey — the 30 Rock and former Saturday Night Live star known for her impression of the ex-Alaska governor.

Palin joked that she's going to play Fey in an upcoming Las Vegas show.

She told Leno's audience she planned to speak at a gun-rights convention: "Be there or else," she warned them.

She said Alaska is different than California. In Los Angeles, "when people have a frozen look on their face, I find out it's Botox."

And she's happy she's not vice-president. "I would not know what to do with all that free time," she quipped.

In remarks taped for broadcast later Tuesday, Palin said the White House health-care plan reminds her of acrobatic flips done by Olympic snowboard champion Shaun White. And she joked that it's so cold in Alaska it's "five degrees below Congress' approval rating."

She had some fun at her own expense, too.

Palin became fodder for late-night TV jokes when she was spotted looking at notes written on her palm during a speech in Nashville, Tenn. She said she picked up the habit years ago from her father, a teacher, and "I'm going to keep doing it."

Earlier, she flashed her palm, which had, "Good evening and welcome to The Tonight Show" written on it.
