There were two friends, a white guy and a black guy. One evening, they were in a bar arguing over which of them could have sex the most times in one night. They decided to settle the issue by going to the local brothel for the evening.
So they got to the brothel, paired off with a couple of ladies, and went to their respective rooms.
The white guy energetically had sex with his escort and reaching up with a pencil, marked a line on the wall. Then he fell asleep. He woke up in a couple of hours and had sex again, albeit a little less enthusiastically. Again, he reached back and marked a line on the wall. And again, he fell asleep. He woke up again in a couple of hours and lethargically had sex again. He drowsily marked a third line on the wall and fell asleep for the rest of the night.
The next morning, the black guy barged into the white guy's room to see how he did. He took one look at the wall and exclaimed, "A hundred and eleven? Ah man!!! You beat me by three!"
