You've never seen Parks and Rec. Quit trolling around.

I really liked the fact that God from Nurse Jackie made an extended cameo in this episode :D

Ah come on! TBBT isn't that bad. It makes for great background TV, you can just watch it passively while doing homework or eating dinner, you don't really need to engage with it to enjoy it.

Hmm, how about watch all three of those shows? Community's obviously the best choice, but given the fact that DVRs and NBC.com/CBS.com/Hulu all exist, there's no reason to deprive yourself of TBBT's fun brand of comedy.
