I just started watching. It airs weeknights at 7 and 7.30 in my area. It's one of the funniest shows I've seen in a long time. I almost had a heart attack when I watched the scene with Leonard and Sheldon in the ball pit.
"If you don't come out of there I'm going to drag you out."
"You can try.... but you'll never catch me!"
Which then lead to Leonard diving in after Sheldon, but having a difficult time trying to grab him.
"BAZINGA!"
My other favorite thus far was when Sheldon and Leonard's pad is robbed, so Sheldon, feeling insecure, decides to relocate to Bozeman, Montana -- which I wonder if it was an indirect reference to Star Trek: First Contact (And also Brannon Braga's place of birth). I laughed so hard when Sheldon first arrives, he's not there thirty seconds and is immediately robbed. He chases after the culprit.
"Wait. Waaaaaait. .............. EXCUSE ME!!"
What I love about Sheldon is he is incredibly smart but at the same time incredibly dumb.
I can't get enough of the show.
