I love the show. I even spotted the guy that plays Sheldon in a gum commercial because I liked his character so much, and recognized him.
It's the commercial where the head of the gum manufacturer implores people to start on their second piece of gum.
Anyway, I missed the first part of that episode. Thanks for posting it, Cyn.
I liked the last part where the Chinese nerds are sitting at their laptop and the same thing happens to their lights. :-P
