Laughter is powerful, that has many benefits. Humor has a place in education, that many don't realize. Laughing helps with retention, it activates dopamine in the brain. Dopamine is is important in motivate and long term memory.
I'm a big fan of humor and use it often with my debate team. When I was teaching them about Counterplans, I started the practice by tell them I had a sheet with everything they need to know about counterplans, and that I even through in the kitchen sink. I then handed out a kitchen counterplan. I had there attention.
About a month later at a tournament, a new debater was asking about counterplans. Joseph, offered to explain them. He said wait a minute, I have a paper with all you need to know. He then handed the kitchen counterplan to the newer debater. He then gave a great explanation of a counterplan.
