WKRP was awesome. And it had one of my funniest moments from all tv lore. They were doing something for the homeless, and had a bunch of homeless folks around Jennifer's (Loni Anderson) desk. One particularly scraggly, old guy gives her a wink, and says, "You know, I'm not as old as I look." She replies, "Oh? Are you any richer than you look?"
I just added Cheers to my list. Don't know why it wasn't there in the first place. SO much craziness over the years. I especially liked the first years. Started off great, with a discussion of the sweatiest movie of all time.
What about Cliff on Jeopardy?

The "Ew"s Diane and Frasier got when they revealed their relationship.
Another of my funniest moments of all tv lore is from the final episode, when Sam and Norm are alone at the end, talking about the important things in life:
Norm: Sammy, I didn't want to say this in front of the others, but... you know what I think the most important thing in life is? It's love. You wanna know what I love?
Sam: Beer, Norm?
Norm: *checks his watch * Yeah, I'll have a quick one.
And some great Norm quotes:

My favorites from there:
Norm: Evenin', everybody.
Everybody: Norm!
Sam: Tell us what you know, Norm.
Norm: God's in his heaven, and something, something, something.
Sam: How about a beer?
Norm: Yeah, that's it.
Rebecca: Have you ever thought what it would be like to be without Vera for 20 years?
Norm: Oh my God!
Rebecca: You see? You'd miss Vera!
Norm: Oh! I thought you said "beer!"
Norm: So, ah, what kinda punnishment ya get?
Frazier: Oh, I'm not getting any.
Norm: Oh, you got off easy.
Frazier: No. I'm not getting any..
Norm: No. You're getting off easy..
Norm: Evenin', everybody.
Everybody: Norm!
Coach: What's shakin', Norm?
Norm: All four cheeks and a couple of chins, Coach.
Norm: Afternoon, everybody.
Everybody: Norm!
Woody: Hey, Mr. Peterson, can I pour you a beer?
Norm: Well, O.K. Woody, but be sure to stop me at one. Ah, make that one-thirty.
Norm: Afternoon, everybody.
Everybody: Norm!
Coach: What'll it be, Normie?
Norm: Just the usual, Coach. I'll have a trough of beer and a snorkle.
Sam: What time is it?
Norm: How many beers have I had, Cliff?
Cliff: Ah...eleven.
Norm: 8:05
Norm: Mornin' Sammy
Sam: Norm! What brings you in this time of day?
Norm: Same thing that always does.
Sam: Little early for a beer, isn't it?
Norm: So, float a cornflake in it.
