A man walks into a bar and asks for a double vodka. The bartender serves him, and watches the man knock it straight back. "Another", says the man. So the bartender gives him another - and sure enough he knocks it straight back again. "Another", says the man again - so the bartender gives him another double and watches him knock it back. "Another", says the man again. By now the bartender is getting a little worried, and asks "Hey, buddy, how come you're drinking so like this?" The man says "Well, today I had my first blowjob." The bartender smiles, laughs heartily and says "Well, in that case, the next one's on me!" So the bartender buys him a drink and watches him knock it back. The man sits there, looking a little disgruntled. "What's wrong", said the bartender. "For a guy who's celebrating you don't look like you're having much fun?" The man looked at him, confused. "Celebrating?" He said. "I'm just trying to get rid of the damn taste."
