Yeah, ive watched the family guy DVD twice i think, and second time round isnt that funny...
example, when Stewie is put into a drama-school, the scene where hes trying to play the tuba, and farts... I had to pause the dvd the first time i was laughing so hard...
i guess if i dont think about family guy for a while and watch it again in a few months it will be histerical again.
Family guy is definately the funniest show around.
dont worry though, the same thing happens to everyone, I absolutely WORSHIP Scrubs, but the original episodes dont have the same effect as they used to.
give it time, and you'll laugh again
