I love the Stewie as Captain of the ship song..

The song where Stewie is the greatest navigator of the ship and he's dressed in blue. God, I love that song. The episode where Brian starts doing cocaine is probably one of the best ever. I watched it twice just yesterday...

"You know what I haven't had in a while? Big League Chew.."

The scene where cousin Jasper dances to "Hot Hot Hot" cracks me up every time I think about it. Classic.
