The nerds of The Big Bang Theory returned to our televisions tonight! It's been several long months since we last saw them. Did anything major happen during the hiatus?

The big news: Sheldon has a girlfriend. Last season left Sheldon meeting Amy (played by Blossom's Mayim Bialik), a virtual she-Sheldon. Clearly their relationship has grown over the summer.

The thought of mini-Sheldons in the world sends a shiver down my spine. Thankfully, Penny put a stop to it (threatening to tell Sheldon's mother will always work) and it will be a while before that threat emerges again.

What were the rest of the guys up to? Wolowitz got his penis stuck in a robot-hand.

Who knew self-gratification could be so dorky? Oh, Big Bang Theory, don't ever change.
