No longer It's Always Sunny in Philadelphia. Hands down, not even close, How I Met Your Mother.
We started watching the current (4th season) season. It sparked our interest enough to throw Season 1 in the NetFlix queue. Similar to Sunny, it takes a few episodes until your in lockstep with the more subtle humor of the show. Granted, it's no where near as irreverent and dark as Sunny. And it's not as unique. However, it has it's own voice and it's got twice as many moments of just flat out, hysterical comedy.
