Whose Sadistic Spectacle is it Anyway?

Dr. X posts this from the Flint Center:

"Saw Brad and Colin's traveling improv show last night, including the famous mousetrap bit (sadistic fun for the whole family). Lots of good stuff. Special credit to Brad Sherwood, who had a couple of good gotchas ('why, this message is six lines of rhyming iambic pentameter - why don't you read it out loud?').

"It's a fun show - they play Tacoma in April."
