The refrigeration truck driver goes into the bar and he asks the bartender “I’d like to have a shot of Gin.”
The bartender decides to have some fun with him.
So the bartender says “All right, what kind of gin would you like?”
The trucker said “You mean there’s more than one kind of gin?”
Bartender says “Sure. You’ve got Hydrogen, Oxygen, and Nitrogen.”
The trucker said “Oh!!!! Well, did you know there are three kinds of turds?”
Bartender says “What do you mean three kinds of turds?”
Trucker says “Well, you’ve got Mustard, Custard, and you, you big shit. Now give me my gin.”
