As an old fart, I used watch Cheers religiously when it was on. I think my favorite character was Norm. Even though if it were real life, Norm's problem drinking would be recognized as ruining his life. Still, Norm was funny and cool - an inspiration for us fat guys everywhere.
I'm pretty certain Cliff was an Aspie. I wish that had been recognized by the writers, so he could have been portrayed in a more positive light like Sheldon Cooper (I don't buy that crap that the writers of BBT didn't intend him to have Asperger's), instead of just being self centered and annoying, and socially clueless.
