All you need to know about Boy Meets World?

This last episode listed in this post is one that I'm still in love with and still makes me warm inside.
Cory's brother Eric is too far beyond great/hilarious, especially in the final season. Buy that season.
Topanga will forever be the hottest thing to come out of ABC Family Channel.

I know there was technically a season one Halloween episode, but it really had nothing to do with the wondrousness of this holiday so I've omitted it. Links below!

Season Two - Who's Afraid of Cory Wolf?

Season Five - The Witches of Pennbrook

Season Five (not really a Halloween one, but scary) - And Then There Was Shawn (this episode also happens to be THE BEST ONE OF ALL)

(If you're into Halloween episodes in general, go on over here and here to read parts one and two of this series.)
