Nerd joke... Einstein, Newton and Pascal are playing a rousing game of hide and seek. Einstein begins to count to ten. Pascal runs and hides. Newton draws a one-meter by one-meter square in the ground in front of Einstein, then stands in the middle of it. Einstein reaches ten, uncovers his eyes, and exclaims, “Newton! I found you! You’re it!” Newton replies, “You didn't find me. You found a Newton over a square meter. You found Pascal!”
