A man goes into a bar and seats himself on a stool. The bartender looks at him and says, Whatll it be buddy?

The man says, Set me up with five whiskey shots, and make em doubles.

The bartender does this and watches the man slug one down, then the next, then the next, and so on until all five are gone almost as quickly as they were served.

Staring in disbelief, the bartender asks why hes doin all this drinking.

Youd drink em this fast too if you had what I have.

The bartender hastily asks, What do you have pal?

The man quickly replies, I have a dollar.
