Super-Colliders, Switzerland and Sheldon on 'The Big Bang Theory' (VIDEO)

Sheldon is soooo excited! Turns out the University is sending Leonard to Switzerland to see the CERN Super-Collider – and he can bring a guest! Well, Sheldon automatically thinks HE will be Leonard's plus-one at the event. "This is incredible!" says Sheldon. "I'm so happy, I'm not even going to question their judgment in picking you!"

Not so fast! Of course, Leonard will want to take Penny, especially since the trip happens on Valentine's Day. But will she be all that geeked about subatomic particle research? Either way, it's just awkward all the way around. Watch 'The Big Bang Theory' on Mon., 9:30PM on CBS.
