[Trust but Verify]

Fawlty Towers

SCTV

The Simpsons

Green Acres

Not necessarily in that order.

Fawlty Towers, SCTV, The Simpsons, Green Acres,

I loved all four of these, but SCTV doesn't hold up too well (on recent viewing). The Simpsons might be the best show ever. I'd add Seinfeld to the list, and early SNL. Andy Griffith was pretty funny, too.
