i don't really care for the south park or american dad shows either, but i really like family guy and i'm not really sure why... i guess sometimes it seems like my family a little bit in that we are all pretty crazy sometimes...
anyhoo, my favorite episode was the one where peter had to have a his colon checked and of course chaos ensues... that is also the episode where stewie gets very attached to lois; when she saved rupert from a nasty dog...
oh and my other favorite was when peter started using a tab at the pharmacy... to be specific my favorite part was when he, brian, stewie and chris drink ipecac syrup and start vomiting everywhere and all over each other... yea, i know, kind of a gross thought, but so funny!
