Two friends charter a floatplane to take them on a moose hunt in Canada. When the pilot drops them off he says, "Now remember, I can only haul one moose out next week when I pick you guys up." They nod and say ok.
A week later when the pilot flies in to retrieve the hunters he sees they killed two moose (mooses, meese?). He explains that the plane won't carry that much weight and they reply, "The guy that flew us in last year loaded the two we got then." The pilot grudgingly agrees to load everything up and fly home. They get loaded up, start across the lake to take off and it becomes painfully obvious that they're not going to clear the trees at the far end of the lake and they crash into the trees. After the hunters pull themselves free of the wreckage, one asks the other where they are. The other says, "About a hundred yards farther than last year."
