Hey sports fans

What is it about being on the big screen at sporting events that makes people go berserk? Kids, I get - waving and staring at themselves. But adults act like kids too - jumping up and down, waving, smooching the person next to them, putting up the "we're #1" finger, etc. It's truly hilarious to me. Then again, I've never been on the big screen - lord knows what I would do.
