Indian walks into a cafe with a shotgun in one hand pulling a male
buffalo with the other. He says to the waiter, "Want coffee."

The waiter says, "Sure, Chief, coming right up." He gets the Indian a
tall mug of coffee The Indian drinks the coffee down in one gulp,
turns and blasts the buffalo with the shotgun, causing parts of the
animal to splatter everywhere, then just walks out.

The next morning the Indian returns. He has his shotgun in one hand
pulling another male buffalo with the other. He walks up to the
counter and says to the waiter, "Want coffee." The waiter says, "Whoa,
Tonto! We're still cleaning up your mess from yesterday. What was all
that about, anyway?"

The Indian smiles and proudly says, "Training for position in United
States Congress: Come in, drink coffee, shoot the bull, leave mess for
others to clean up, disappear for rest of day."
