I will start my collection of math humor with Abbott & Costello. For Abbott and Costello loved to perform funny mathematical routines. Some they performed in different settings. I once heard that they had a mathematician among their writers. Many of their mathematical skits are quite famous. I think that their most famous routine, Whos On First’ is funny because of its mathematical point of view (I will explain it in that post.)

Can you figure out why these skits are so funny? What is wrong with the math and how to fix it?
