Once there was a homeless person named Santa Singh . One evening a tourist saw him lying asleep on the street on the cold  and out of pity, put $20 next to him. When Santa woke up after a while , saw the money and he straight went to a local bar and asked what can he get for that amount.

"Try this", said barman, and mixed him up a dry martini.
He thought it was great and he felt warm and  about an hour later, he was asleep on the street, dead drunk. The same tourist was returning back drunk from a party and saw santa lying on the street and he thought of giving him a quickie in his ass while he was out cold. After that he again put $20 dollars next to him. Next night, Santa returned to the bar and got stuck into the martinis again. As before, he finished up dead drunk. The same guy had his way again with his ass. This went on for a week.
When Santa came back on the eight night, the barman started mixing the martinis as soon as he walked through the door.
"Can I have a scoth tonight!", he said. "Those martinis make my ass sore!"
