You know the riddle, 'How many <blank> does it take to change a lightbulb?" Well, here's one for Cheers.

Norm- Will do it, but only if he's offered free beer and pizza.

Cliff- Will do it, but not until he's spent several hours telling us little known facts about the lightbulb and related stuff.

Carla- Won't be able to change the lightbulb because she just shoved it down Cliff's throat to get him to shut up.

Frasier- Will try to analyze why people feel the need to change lightbulbs.

Sam- Too busy combing his hair and flirting with women to change the lightbulb.

What can you guys come up with?

Diane: won't do it, too busy trying to make Sam jealouse by going out with some 20 year old and bickering with sam about the type of women he's dating .

Paul: will do it because cliff will

Robin Coldcort:Will do it because he wants to show how much more "rugged" and "macho" he is than sam

Rebecca: Will do it because Robin will do it.
