Not necessarily the best episodes, just the best title.

I'll go with one per season....

1. Pick A Con.... Any Con
2. Fortune & Men's Weights
3. The Heart is A Lonely Snipehunter
4. Birth, Death, Love, and Rice
5. I Do, Adieu
6. Bar Wars (duh!)
7. One Happy Chappy in a Snappy Serape
8. The Stork Brings a Crane
9. Norm and Cliff's Excellent Adventure
10. One Hugs, the Other Doesn't
11. One For The Road / The Bar Manager, the Shrink, His Wife and Her Lover (tie)

One Happy Chappy in a Snappy Serape- Hand's down.

I'm partial to "Birth, Death, Love and Rice" and "One Hugs, the Other Doesn't"

Hmmm, interesting question!

For some reason I've always liked "Rebecca Gaines, Rebecca Loses." It just sounds catchy! And, of course I feel obligated to say "Chambers vs. Malone," since it's my user name. ;) I do like that title, though, because it's so apropos for Sam and Diane. "Homicidal Ham" is also pretty clever. ;)
