A man walks into a bar and brags to all the patrons that he can taste and identify correctly what any drink is blindfolded.
The bartender and a few patrons wager on this claim and proceed to blindfold the braggart and serve him the first drink.
The man says " Oh yes, Jack Daniels and Schweppes Ginger Ale with a orange twist".
The patrons and the bartender are amazed. So the bartender mixes another libation.
The man says confidently " Oh glory be, a Dirty Beefeater Martini straight up with a lime twist".
Once again this happens for the third time .The man is right on the money again and nails the drink's content and is getting louder and arrogant. He boasts "A Black Russian with Grey Goose and Kahlua". Is that the best you've got"?""What a bunch of losers in this bar!!" "Come on now lads double or nothing"!!!!
So now the patrons and the bartender are getting upset and very suspicious.
Then the bartender comes up with an idea and decides to urinate in a glass and see what the man identifies this drink as!! He says to the patrons in a whisper "I'll show this bragging bastard a drink he will never get right!"
So the man drinks the drink and practically vomits it all up and exclaims "THIS TASTES LIKE PISS"!!!
With that said the bartender replies,"Yea but whose is it"?
