I like this video because it reminds me of some facts that are similar in nearly all mothers and fathers and teachers even. Mothers. Most are similar in some ways. They care about how things look around the house (like in the video, she's telling Bill to clean his room) and they always made sure their children are clean or at least most parents (like in the video, Bill is talking about the part of clean underwear). As for Fathers. They are different than Mothers (like what the video said) but in a weird kind of way. As for some teachers I have met, when they get angry, they starts yelling at the students and through those yelling, you will catch some questions and students who try to answer, get yelled even more. 
I like this video not because it's funny but because it's true. I barely hear grown ups talk about their parents like this. Children talking to their friends in that way is more normal but a grown up, it's just interesting and weird. I like Bill Cosby and his stories.
