Well, I've been counting and they've showed every episode they ever had three times each. It's getting so that if you see one episode, you can pretty much guess (quite accurately) the rest of the week.
As for "Washing the Dog", I noticed this the second time they played it. They edit out the entire scene between when the old lady leaves and when they appear on Anderson's doorstep. They didn't even show them washing the fucking dog!
What the hell is with MuchMusic? They kinda seem schizophrenic. They'll play At the Movies, for example, and then play an edited Wasing the Dog. I wish they'd get new shows and decide which side of the fence they are on.
