Nothing he says is funny.
From a college student's perspective, he's still not funny. I showed some of his clips to my frat and soriety people and they don't get what he's saying.
I think you need to go lower than college students, maybe high school students will find him funny.
Actually, I don't know if high school kids will find him funny either.
In my honest opinion, you need to go as low as 7th grade, that's where he can make them laugh.
