Einstein, Newton, and Pascal are hanging out one afternoon
Einstein is bored, so he suggests they play hide and seek
The others agree, so Einstein begins counting
Pascal runs off right away to find a place to hide
Newton takes out a piece of chalk and draws a mid-sized square on the floor around him
Einstein looks up and immediately spots Newton standing right in front of him.
He says, "I found you, Newton!"
Newton replies, "No, you found one Newton per square meter - You found Pascal!"
