I will recommend the funniest joke. One day, a mathematician and his friend went to watch a movie. While they were waiting for the movie to start, the mathematician asked his friend,"do you know why mathematicians like to go to the movies?" His friend was a little confused but still replied,"Don't you know why?" The mathematician replied," Because movies are a way for people to relax and mathematics is a way for people to relax." His friend was very surprised, but he still tried to understand what the mathematician was saying. Finally, he understood what the mathematician meant and smiled." Oh, I see. You mean mathematicians like to watch movies because they like to relax and you don't." The mathematician replied," No, I mean mathematics is a way for me to relax." This joke used the similarities between mathematics and movies to express this concept in a humorous way. I hope you like it!
