Sure thing.
Royal Canadian Air Farce (just known as the Air Farce) is a half-hour sketch comedy show on the CBC. They do parodys, a lot of political commentary, crazy characters, and original sketches (Like Jimmy and Seamus, the Donut Shoppe, Gilbert Smythe-Bite-Me, Jock Mc Bile's Get Stuffed (before that actor passed away), and tons of others). Their website is airfarce.com and they actually have alot of info, old clips, tons of stuff.
22 Minutes is similar. It's full title is This Hour has 22 Minutes, and it is a satirical news program. They do alot of sketches too, and their show is alot more political that Air Farce is. And each cast member has a crazy made-up newscaster name. Cathy Jones' is Cindy Dubisnchick or something like that.The comedy is a little more biting and less goofy, mostly social commentary. Some of their sketches include Marg the Warrior Princess (Mary Walsh dressed up like Xena with a lisp chasing politicians), the black and white commentary that Rick Mercer did, the crazy donut lady, the old native man, the two old ladies walking through the park, That Show Sucked, Mary Walsh dressed like a greasy sexist man. Also on the CBC.
This Sitcom is not to be repeated is on CTV, and I haven't seen it very many episodes. It's a half-hour comedy show, but the difference is this one is all improv!
