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. However, Newton merely takes out a piece of chalk and draws a mid-size square on the floor. 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!"
