Back in the day, my friends and I would stay up late and watch Saturday Night Live (back when it was actually funny!). After SNL (so, like at 1am) was SCTV; a Canadian comedy show that introduced us to Great White North with Bob & Doug McKenzie (Dave Thomas and Rick Moranis). The show also gave us our first glimpses of John Candy, Martin Short, Eugene Levy, Harold Ramis, and other really funny people.
One of my favorites was Joe Flaherty and John Candy in Count Floyd's Monster Chiller Horror Theatre. Here's a sample... Dr. Tongue's 3D House of... Pancakes. Scarey!!!
