Pede. Rogan did not write Knocked Up. He only wrote one movie that led to his success, Superbad, which I personally thought was awful. This Is The End was worse.

Rogan has gotten fame and fortune from the writing efforts of others. The only things he's written are poorly disguised fantasies of his, like Superbad and Pineapple Express (hurr, duuuuuuuude, smoke weed and high school girlfriend, huh her hur!)

I've yet to see examples of his so-called writing prowess.
