House M.D.
The Office (US Version)
Two and a Half Men
It's Always Sunny in Philadelphia (Inbetween Seasons)
My Name is Earl (It has unfortunately gone downhill)
Most TV shows I actually don't watch week to week, I just eventually wait for 5-10 seasons to be out on DVD and then watch them back to back.

And my fallback is Mystery Science Theater 3000... (Other shows not currently on, Red Dwarf, Buffy, Stargate SG-1, Star Trek:*, Wonderfalls, Doctor Who, etc...)
