Arrested Development
Moonlighting
Simpsons (first 7-10 seasons)
Cheers

Soap
South Park

Angel
Firefly
The Avengers (Emma Peel seasons)
Babylon 5
Jeopardy
The Tonight Show with Johnny Carson
Big Bang Theory
Rocky & Bullwinkle
Friends
Freaks and Geeks
Firefly
Friday Night Videos
The Amazing Race (damn - I was hoping all 10 would start with F)
Mad Men
21 Jump Street
Star Trek: The Next Generation
X Files
Sopranos
ETA: Can’t believe I made the same joke as MoonMoon
The majority of mine seem to be recent, but that’s probably because my tastes have changed and I look back on most older shows less fondly compared with the golden age of now (whenever “now” may be).

Maybe there could be separate lists for favourite “kids” show and “grown up” show. I could’ve had Tom and Jerry, Top Cat and Marine Boy in there, but also Blackadder, Python, House, Psych and The Mentalist… But do all those belong in the same list? Oh well.
Roseanne (funny)
Moonlighting (celeb crush)
The Office (funny)
Dick Van Dyke Show (comfort show)
The Golden Girls (comfort)
All in the Family (comfort)
The Monkees (crush)
Andy Griffith Show (comfort)
Bob Newhart Show (comfort)

Only the first three did I watch in real time. The rest caught on Nick@Nite and cable, etc.
