What jokes are scenes made up with your brain that make you feel like laughing until your stomach hurts?

My uncle used to help my cousin buy shoes by measuring the size of old shoes. This time, I just took my cousin to the street, so I didn't bring a size bar. As a result, when I bought shoes, I asked my cousin to try them on. Obviously, they are suitable, but he insists that they are not. He stopped wearing it after buying it, so he had to take a size strip to measure it. That's all he believes. The shoe store owner argued with him, but he never compromised. My uncle couldn't help it and attracted all the people who bought shoes to watch.
