You're trying to hold in a crap while rushing to get to a toilet. The knurled protuberance of a turd pokes out of your anus. You are able to retract it back in. It repeats over-and-over again until you are finally able to fully relieve yourself at a toilet. This repetition is a Puppet Show.
I need to pull over and find a restroom because I've got a real Puppet Show going on right now.
