While eating, Raj comments that there's not a vegetable in sight. Howard says that's not true because there are tomatoes in the ketchup packet. This should have invoked a response from Sheldon - in a previous season he was shopping with Penny and commented that tomatoes, while in the vegetable section, are actually fruits.
Sheldon holds the magazine one-handed when he shows it to Leonard. In the next shot, he holds it in both hands.
In The Bakersfield Expedition (2013) in season 6, Amy, Penny and Bernadette have a debate over the comic book character Thor. In this episode during the discussion at the dinner table, Penny doesn't seem to recognize the name Thor when Raj says it, but this may just be due to his pronunciation of it.
Because of the power failure, Howard's home is lit with 6 menorahs, and other candles. Menorahs only accept thin Hanukkah candles that burn down quickly. Throughout the evening, the candles all appear to have been lit just minutes ago.
Wolowitz, being an engineer, should have known not to open the freezer door during a power outage. He knows the power failure will be over relatively soon, and by simply leaving the door closed the items in the freezer would have been just fine. Instead not only does he open the door - he stands there with it open while he talks about how the food will soon spoil.
Based on what Stuart got from the power company, power would be out more than 24 hours. Too long even if the freezer door remained closed.

As a microbiologist, Bernadette should know the danger of refreezing defrosted food.
