This week's Big Bang Theory is going to be a rerun, but here is a look a head to next week's episode, "The Cornhusker Vortex":
Sheldon teaches Leonard how to understand football while a kite-fighting incident threatens Howard and Raj's friendship.
I have a few questions about this. How does Sheldon know about football? Why does Leonard even want to know about football? Where are Howard and Raj going to fight kites in the city? How can kite fighting even be remotely controversial?
