A guy runs into a bar and says, "Bartender, quick! Give me 20 shots of your best Scotch!"

So the bartender lines up 20 shots of his best Scotch and watches this guy down one after the other.

"Man," the bartender says, "I've never seen anyone drink shots that fast!"

"You'd drink them that fast too if you have what I have," the guy says.

"Oh my God," says the bartender, "what do you have?"

"50 cents."
