Prime Minister Stephen Harper is in Saskatchewan this week for business and perhaps a few laughs, during shooting for a cameo appearance in the popular TV show Corner Gas.

He's also scheduled to attend a Conservative party barbecue on Tuesday evening.

So far no meetings are planned with any provincial politicians.

Premier Lorne Calvert has been pushing Harper to keep an election promise to amend the equalization formula.

Earlier this month, a letter was leaked to the media from Tory MPs in the province. It also urged Harper to keep that promise.

Meanwhile, Harper's appearance in Corner Gas isn't the first time the CTV sitcom has featured Canadian politicians in walk-on roles.

Calvert appeared in an episode that aired last December where he played himself and almost got hit by a thrown newspaper.

The show has also featured cameos by former prime minister Paul Martin and Saskatchewan MP Ralph Goodale.
