The little turtle replied, "I will, if you don't drink my coffee."

Three turtles decided to have a cup of coffee. Just as they got into the cafe, it started to rain. The biggest turtle said to the smallest one, " Go home and get the umbrella."

"We won't," the other two promised.

Just then a voice called from outside the door, "If you do, I won't go."

Two years later the big turtle said to the middle turtle, "Well, I guess he isn't coming back, so we might as well drink his coffee."
