Two hunters hire a small plane to take them to a remote area of Canada. Upon dropping them off, the pilot warns, "Remember, only one moose. The plane can't take off with more weight than that."
A week later, when the plane returns, the hunters are standing by the lake with two moose. The pilot fumes, "I told you only one moose! You'll have to leave one behind." "Oh, come on," the hunters beg, "Last year's pilot let us take two. You're just a chicken."
Not wanting to be called a coward, the pilot reluctantly agrees. The plane strains across the lake, struggling to take off. Despite repeated attempts, it crashes into the trees at the lake's end.
Later, one dazed hunter gets up, looks at the scattered debris of the wreck, and asks, "Where are we?" The other replies, "Oh, I'd say about a hundred yards farther than last year."
