Rogen's character
Seth Rogen's character is based on Judd Apatow when he was a young comedian. I actually saw some Apatow stand up from the 80's on a HBO Annual Young Comedian special and he uses some of the same jokes.
"I'm not good looking, but I'm not bad looking. So if I had a good personality I could get any girl I want, but I dont."
Brilliant writer, awful stand up comedian.
