A little geek humor....

[David M]

Einstein, Newton, and Pascal are hanging out one afternoon. Einstein is bored, so he suggests, "Let's play hide-and-seek. I'll be it!" The others agree, so Einstein begins counting. "One... Two... Three..."

Pascal runs off right away to find a place to hide. But Newton merely takes out a piece of chalk and draws a mid-sized square. He finishes and steps into the square just as Einstein shouts, "Ready or not -- here I come!" 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!"
