One of the things that the crew used to do quite often is create and perform a song or two. Some of these had direct connections to the movie they were watching. Tom's song about Tibby the Turtle from Gamera is one example. Other times the gang went nuts with a song for no reason. The whole swing choir challenge from The Skydivers is a perfect example of that.
One of my favorite songs is the Tribute to Pants. They boys have been watching Hercules Against the Moon Men, and were subjected to several scenes where men in togas or tunics bend over, fall down, or climb somewhere exposing areas that Joel and the bots would rather not see. As the first break rolls around, Joel and bots have had enough and come up with this song. Enjoy!
