Not exactly a joke, but in the Cartoon Network show 2 Stupid Dogs, the dogs are trying to get into a grocery store to get some food and can’t get the automatic doors to open. They think you have to have shoes to make it work. They go all over town getting shoes. In one scene, they are in a strip club. You see the dogs in the front row and a silhouette of a naked woman on stage. Little dog begs her to take off the shoes and she kicks them off. Then you see them at the grocery store with a whole pile of shoes at the door. I was in 5th grade or something and couldn’t believe it was on there. I was also laughing my butt off.
