This is exactly why I watch this series. That was the only classification I can think to put of for this episode. Everyone was great, even Johnny Galecki was less annoying than usual. Simon Helberg continues to bring life to an excellent character in Howard. Kaley Cuoco isn't as good on this show as she was on 8 Simple Rules, but she was still funny as well this week. Rajeesh provided some laughs, but like always Jim Parsons stole the show as Sheldon.
The scene where he was pretending to work at the electronics store was great. Telling the woman that it's out of stock but they can order it for her was great. Somehow he seems to get funnier every week.
The Big Bang Theory continues to be the top comedy on Monday and is slowly rising in the rankings toward the top sitcom on television. If they keep producing quality episodes like this they might reach 30 Rock and Curb Your Enthusiasm one day.
