„at the Engvalls' home, Travis is about to play on the piano.
Engvall's son, Travis: I'm going to play you a song from Harry Potter.
Engvall: Oh, the movie?
Travis: No, the book. Here's your sign.
When telling the joke on Here's Your Sign: Live! (2004), he stops his son before he says "sign."“
— Bill Engvall American comedian and actor 1957
