I like how this episode shows how the house changed after Germany. My favorite parts were how Missy and Mary connected after Taylor broke up with her, and the hidden reference to the Big Bang Theory that explains why he knocks 3 times, and I am not sure very many people understood. I also liked Sheldon's new friend and how he kept talking to him, even though he never knew anything about him. It was funny when Sheldon said he fell asleep in the hallway on the way to get a Yoo-hoo. Also, when Sheldon saw there was a bathroom schedule, and accepted that it was Georgie's turn to go to the bathroom.
