The theme from "The Andy Griffith Show" is about the best there is.
Just whistle it once and see your friends get stuck with it for the rest of the day.
There was a reality show years ago...I cannot for the life of me remember the name, but one of the "challenges" was for one person to spend time in a small room with nothing in it and listed to "Tiny Bubbles" over and over again for 24 (I think) hours. Talk about torture! Anyone remember that show? I seem to think it was a bunch of people that lived together in a place with no windows, doors, or clocks so they had no idea what day or time it was. Each day (or week?) they would get the option to leave. I think the last one standing got a million bucks or something. I think it was that show that featured the Tiny Bubbles challenge, but it's possible I'm mixing up 2 different shows.
ETA: I just googled and found out that the Tiny Bubbles challenge was from an episode of The Mole, which I loved before it went celebrity and the other show was called Unan1mous.
