Two guys attending a baseball game in the middle of July were sitting in the bleachers when one turned to the other and said "take a look up there" motioning to a rather heavyset woman sitting quite a few seats higher up than theirs with her legs propped open.
The second guy took a good look and said, "wow, I don't believe it, I don't think she has any underwear on".
"Can't be" said the first guy, "It's probably just black underwear".
The second guy gets up, sprints up the steps to get a closer look and comes back down to sit beside his friend.
"Nope, we're both wrong, it's flys"!
