I just found this on the Raider board on Yahoo
Three football fans were on their way to a game when one noticed a foot sticking out of the bushes by the side of the road. They stopped and discovered a nude female dead. Out of respect and propriety, the Rams fan took off his cap and placed it over her right breast. The 49ers fan took off his cap and placed it over her left breast. Following their lead, the Raider's fan took off his cap and placed it over her crotch. The police were called and when the officer arrived, he conducted his inspection. First, he lifted up the Rams cap, replaced it and wrote down some notes. Next, he lifted the 49ers cap, replaced it and wrote down some more notes. The officer then lifted the Raider's cap, replaced it, then lifted it again, replaced it, lifted it a third time, and replaced it one last time. The Raider's fan was getting upset and finally asked, "What are you, a pervert or something? Why do you keep lifting and looking, lifting and looking? "Well," said the officer. "I am simply surprised; normally when I look under a Raiders hat, I find an asshole."
