Grasshopper

A man walks into a bar and asks the bartender to recommend a good drink. The bartender says that their grasshoppers are very good, so the man orders one. Then he has another couple.

On the way home he notices a grasshopper on the ground. He says to the grasshopper, "do you know that there is a drink named after you?"

The grasshopper looks up at the man and says "do you mean they have a drink called Irving?"
