Play hide and go seek
Einstein, Newton and Pascal are playing hide and go seek.
It's Einstein's turn to count so he covers his eyes and starts counting to ten.
Pascal runs off and hides.
Newton draws a one metre by one metre square on the ground in front of Einstein and stands in the middle of it.
Einstein reaches ten and uncovers his eyes.
He sees Newton immediately and exclaims, "Newton! I found you! You're it!"
Newton smiles and says, "you didn't find me, you found a Newton over a square metre. You found Pascal!"
