I don't remember titles, but I like all the ones where Death is involved and the Brian/Stewie adventures.
I didn't know the titles either for most of them, I had to look them up on Wikipedia.
Oh yeah the bank vault episode sucked too. THERE. WERE. NO. CUT-AWAY. GAGS. WTF
The part about Stewie's diaper was what makes me hate this episode. One of the few times in my life I wondered how Standards and Practices allowed this to air.
I once told someone at work I liked Family Guy, he said he didn't like it and this episode was the first thing he mentioned. I guess I'm guilty by association.
