A kid walks into a lunchroom at school and sees a fly on the table. He swats it and leaves.
Abother kid walks in, sees the dead fly and says, “Hey, cool, wings.” So he pulls off the wings and leaves.
Another kid comes in, sees the fly, and says, “Hey look! Legs!” So he pulls off the legs and leaves.
A third kid comes in and he also sees the dead fly. He leans over to look at it and pulls of its head.
Then the first kid comes back, sees it and says, “Hey, look, a raisin,” and he eats it.
