In the interest of scientific accuracy, I must point out that flying fish definitely do fly, or at least glide for extended distances, as can be seen in any number of Youtube videos. Thank you, I feel better now.
Similarly: Fermat, Newton and Pascal play hide and seek. It is Fermat's turn to search the others, he covers his eyes and starts counting. While Pascal runs away and hides, Newton takes some chalk and marks a square on the ground with a side length of exactly 1 meter, then sits down inside the square.
Fermat finishes counting, opens his eyes and shouts "I found you Newton!"
Newton: "No, you found one Newton per square meter, you found Pascal!"
