I heard it was pretty funny. I almost saw it with my brother and sister but I was dead set on seeing Quantum instead. I will see it when it hits DVD though.
Sarah Marshall jumped to the top of the list of Apatow for me when I saw it. The greatest character of all time, Aldous Snow was created in that movie. He even has his own movie coming out next year. I'm a giddy school girl for that one.
