Materials:
Three plump pigs
Three pieces of paper
A tingle of tape
A moonbeam of markers
A crescent of cleverness
A dollop of deviousness
A boatload of balls
A crater of not getting caught

Directions:
In order to pull this thing off you are going to need a boatload of balls.
Next, Sift the crescent of cleverness with the dollop of deviousness.
Fuse the boatload of balls with the sifted crescent of cleverness and dollop of deviousness. You're really going to need this.
Take your three pieces of paper and lay them on the table.
Then, snatch the moonbeam of markers.
Using the moonbeam of markers write down the numbers 1,2,4 on the pieces of paper.
Use a tingle of tape to tape on the pieces of paper to the plump pigs.
Let the plump pigs run loose at lunch that day.
Finally, after they catch plump pigs 1,2,4 watch as they search for plump pig number 3 (who seems to have vanished).
