Family Guy Seasons 1 - 4 (rest is shit, I know it, you know it, no need to fake it)
South Park
It's Always Sunny In Philadelphia
Curb Your Enthusiasm!!!!! Probably the best show ever made (except around Season 5)
Flight of the Conchords (you have to get into it. Persevere and epic lulz will be had)
The Office UK (US is also ok). How one can invent the character of David Brent is really beyond me. Stroke of genius, period.
Desperate Housewives was also really good, Season 1 is awesome, then it goes down a steady slope, but Season 5 is again great. Never finished season 6 because = lame.
For those unfamiliar with Curb, here's three of the most epic scenes imo.
Larry David vs Bluetooth guy
