I dunno, Peter Venkman was a goof but he didn't go as far as to pretend to drunk drive the Ecto 1 for his own amusement.
For the record, I never actually liked FAMILY GUY, and the only movie of his I've seen was TED, which again didn't find all that funny. I don't have a hate boner for him like so many seem to, its just that his brand of humor never worked for me.
I did like his hosting of the Oscars, but that's largely because most Oscars programs are so stale that him just making fun of it and Hollywood in concept was refreshing, which of course everyone hated because Hollywood doesn't like mockery.
