I thought that was one of the funnier episodes of the season, but then again, I've enjoyed all of the episodes with Wolowitz and Bernadette very much. That actress has fit right into the group with a distinct personality-- a hardcore nerd who isn't steeped in pop culture geekiness -- she's like another, less explored facet of nerddom. BTW, does Bernadette remind anyone else of Georgia Engel?

The Penny and Sheldon interactions are always gold, and I have begun to notice and appreciate the subtle Texas Twang that comes out when Sheldon is at his most flustered.

And another hilarious Wolowitz and off-camera mother scene to top it all off.

Kind of sad for Johnny Galecki that the show is at it's best when Leonard is shoved in the background. Wolowitz and Raj >>>>>>>>>>> Leonard. Even Bernadette >>>>> Leonard.
