Tonight's episode was no different. The episode involved Penny starting a buisness selling hair barettes and enlisting Sheldon to improve her efficiency. The premise may be somewhat silly, but the writers definately delivered some solid material.
The episode has several highlights, specifically Sheldon's classification of coffee as a "gateway drug." It absolutely fit Sheldon's rigid views on life, caffine is a drug, therefore he can't drink coffee. It was also nice to see the writers reference Sheldon's extreme fear of his mother yet again.
This was a pretty Sheldon heavy episode overall, but they didn't overplay that card. He is probably the funniest character on the show, but this show has certainly been guilty of using too much of a good thing with Sheldon, and making it seem corny. Some good Leonard, Raj, and Howard moments watered down the Sheldon craziness and really made this episode.
Unfortunately, the "Sheldon on caffine" scenes were a tad too predicatable. The scene of him as The Flash was worthy of a chuckle, but not really up to this show's standards. Also, the cold ending wasn't quite up to snuff either. Just a bit too over the top, even for the geeky friends.
Overall, a solid episode. Not exactly on par with the Christmas episode, but certainly a solid episode. No drop down, roll on the floor laughs, but plenty of funny moments to fill the half hour.
