There was this guy called Mr. Dressup. He had a "tickle trunk" in which he had any number of costumes he might put on in order to do little plays or whatever. Um... there were puppets on the show. One was a kid named Casey and one was a dog named Finnegan. And I guess they'd do plays with Mr. Dressup. I don't really remember the show clearly at all, but I occasionally watched a bit of it, so, you know... it's a part of my youth. Or whatever.
