I think it takes about halfway into season 2 to get HOOKED.

Season 1 was fun, but they don't really get it right until a few eps into season 2.

The first episode of season 2 is American Duos which is easily one of the overall best episodes of the show.

If the second season doesn't hook you none probably will.

These episodes are my personal favorites of the series so far and worth a watch if you don't want to watch the entire series.

American Duos
Bounty Hunters
Daredevils
Let"s get Hairy (especially if you're An American Werewolf in London fan)
High Top Fade-Out
Viagra Falls
This Episode Sucks
Lassie Jerky

Love the show always makes me laugh

I always like the "scary" episodes the best, for some reason. My favorite is Tuesday the 17th, I've seen it like 20 times xD
Some of my other favorites are:
Scary Sherry
65 Million Years Off
Shawn (and Gus) of the Dead
Ghosts
The Yang episodes
Dual Spires

I'm not going to list all of them xD
So many good ones.

Apparently season 8 is going to be the last. Juliet will only be in 5 of the 10 episodes and starting in the 7th episode, I think, Lassie is being replaced by a new head detective. What that means for him, I don't know. Maybe he becomes chief or maybe he moves away (like Randy in Monk). I can't see them actually killing off any main characters.

"Steve Franks and JAmes Roday have both alluded to in seperate interviews that season 8 is the last. "
