A Lions fan, a Chiefs fan, and a Bears fan are walking down the street when they come upon a woman laying on the sidewalk.  She's stark naked and on her back with her eyes closed, completely passed out.  The guys quickly call the cops, and stand by the woman to guard her while they wait for them to arrive.  Well, while they're waiting, the Lions fan decides to take initiative.  He takes his Lions hat off, and places it over one of her breasts to cover her up.  The Chiefs fan follows his lead, taking his Chiefs hat off and placing it on her other breast.  Reluctantly, after one last gander, the Bears fan places his Bears hat between her legs.  A short time later a policeman arrives, and he thanks the men for their gentlemanly and moral behavior.  He calls for an ambulance, and takes a glance towards the woman.  He stares at her with a long gaze of disbelief, even leaning over her to look at her crotch, then shakes his head.  He still can't shake his disbelief though, and leans over her again, this time lifting the hat between her legs to examine the woman's vagina, then replacing the hat and shaking his head once more.  "Hey, what the hell?!" the Lions fan says.  "What do you think you're doing?!"  The cop throws his hands up,  "hey, I'm sorry, it's not what it looks like," he says.  "It's just that I've never seen anything but an asshole under a Bears hat."
