Howard made a robotic arm unpack the gang's dinner. It may have taken 28 minutes, but it was worth it. Now we want one. But, as Sheldon so appropriately points out,"We must be cautious. Today, it's a Chinese food retrieval robot. Tomorrow, it travels back in time and tries to kill Sarah Connor." He really does get the best lines. We love that Wolowitz is using his robot, which is designed for use on the space station, to do something this mundane.
This isn't a novel thought, but Sheldon and Penny together is just awesome. He belittles her in almost every way possible, but they still manage to make it funny. Bravo.
We're pretty sure everyone knew where Howard having a robotic arm was going, but it was still pretty funny to watch. The end tag was great, too.
