This one might also be a little... edgy, so all you PC people, just keep on scrolling.
Three men are sitting in a bar: A Texan, who orders beer, a Mexican, who orders tequila, and a Washingtonian, who orders a bottle of water. Suddenly, the Texan throws his beer up in the air and fires a shot through it. He tells the stunned patrons of the bar, "don't worry; where I come from we from, we have plenty of beer".
Not much later, the Mexican does the same with his tequila, saying, "don't worry; where I come from, we have plenty of tequila."
A few seconds later, the Washingtonian shoots the other two men, drinks his water, and puts the bottle in his pocket. "What did you do that for?!" people screamed.
"Well, where I come from, we have plenty of Texans and Mexicans, but I really should recycle this bottle."
