Rudolph the red nosed rein-sheep
Had to stand on just three feet
This made his A.I. program
Always run NP-complete

All of the other rein-sheep
Used to call him names and laugh
They always said poor Rudolph
Had an asymmetric graph!

Play "Rudolph Shepherds the Flock".

Instructions: Move Rudolph by dragging your mouse, so he can bring all the other sheep to a holy place.

(and make sure you have your audio turned on!)
