Yeah it was so cool.
And I also liked it that he asked her for help.

Loved them in the lastest episode too. She touched his hand and then she was like : "That´s sticky!" it was so much fun to watch that scene
I don`t know with what Sheldon washed his hands before they went to the hospital Oh wait : He was eating those sticks or something when he was in the car with Amy and forgot to wash his hands
