And since he was as dumb as a box of rocks, I hated most of the stuff he liked. While he'd laugh at Leonard and Sheldon's first season antics I was wondering when more reruns of Star Trek would be on and how my guild in World of Warcraft was fairing on their latest raid. You know, important stuff.

First off if this show offends you GOOD. You are weak person don't have children because we don't need anymore fingers in the pudding. You forgot how to enjoy yourself and laugh, at that point your life is not worth living and you should check out early. No body likes people who cry about everything or only looks for the negative just watch CNN because you cant think for yourself. Your not clever its not a new thing to wine about stupid things to think your edgy and hip. NO BODY CARES.. with that said this is a good show.

This show is funny and clever with all the characters showing development in there personality's . I don't know how the reviewer Izy comes to the conclusion that this show is politically incorrect considering the spectrum of the characters background and the balance of casts sexuality and religious beliefs or lack of in some cases, two gay,one Jew,one Hindu, one atheist, a couple of agnostics, one over the top christian. I am sure I have missed some characters (sorry).love the show may it continue forever
