“What has two legs, a tail, and bleeds profusely?”
“Half a cat.”
My informant got this joke in high school. It was everyone’s favorite joke in her Theater class. Sometimes they would just text each other “Half a cat”. The informant says that she thought it was funny in an unexpected and twisted way. It was mostly funny because it was an inside joke within the theater group. She said it in-jokes were in common in her theater class, they wouldn’t make sense to people outside the class.
This is kind of a joke riddle. The humor comes from the fact that the person thinks the answer is going to something they don’t know but then the answer is actually really simple. It actually reminds me of a joke from one of my favorite books How NOT to write a Novel “Giving a reader a sex scene that is only half right is like giving her half of a kitten. It is not half as cute as a whole kitten; it is a bloody, godawful mess ” (Mittelmark and Newman) Apparently in American society dead cats are a source of humor.
