Guy at work and I just came up with this. Get a copy of Rock Band, and have the real band whose song is on it to try to play it. See how many bars they get through before the audience starts booing and the players throw the instruments down in disgust.

If I had a show, every time I had a band on I'd make them do that. I love when Peart says, "I can't play that thing." And Lifeson you could tell was missing stuff all over the place. Didn't catch who said at the end, "They hate us. We suck."

Now every time someone at a party says, "Oh, you should be good at this!" I'll know where to point them.
