Good list. I will agree with listing Seinfeld, All in the Family, West Wing, Mash and Cheers. I would throw in Fraser, Hawaii Five-O, ER, Happy Days (pre-shark), and CSI (Grisham only).
The shows on this list all suck except for Seinfeld.
Mr Ed and Gomer Pyle has them all beat, no to mention Andy Griffith.
