...They are making cracks at the cheerleaders.
...Guys are slipping in their own drool.(due to the cheerleaders infront)

...By the same token, they forgot their sunglasses and cannot see.
...They are trying to adjust their flipfolder which somehow only has one ring on it now.

...They decided it would be more fun to chase the mascotr down the street.
...They are off bribing the judges.
