There's a video on YouTube of some guy at a college party who brought a girl up to his room . . . and forgot to close the WINDOW BLINDS. So everyone in the backyard can see them.
His shirt is off, and he might have been PANTSLESS too, but you can't tell. And the crowd outside keeps cheering for the girl to take HER shirt off. Luckily she finally realized what was happening, and both of them duck out of view.
