Krispy Kreme and Cheerios
Fred, Bob, and Mike were driving down the street when they saw a hooker on the side of the road. They pulled over and the hooker said, "If you want to, you can come back home with me."
The guys were really horny so they all went back to her apartment.
Fred went in the bedroom with her first. He came out a half an hour later and said she put a powdered donut on his dick. Bob went in next and came out a half an hour later and said she put a glazed donut on his dick.
Mike went in next and he came out five minutes later. Fred and Bob asked, "Did she donut you? Did she donut you?"
Mike said no and looked at his hand which held $2 and said, "She told me to go and buy a box of Cheerios."
