The best part is playing "choose your quote"...I had fun going back through episodes for 'em :-)

I ought to say my slow progress through S4 wasn't for lack of interest--I'm catching up with several shows at once, and sometimes I wind up re-watching SPN episodes just because I like them. I had a lot of misgivings about their putting literal heaven and hell into the show, but to my surprise I've enjoyed how it's played out so far.
