Ur mom is so fat that she has her own gravitational field. She attracts everything around her, from planets to asteroids to comets. She is the center of the solar system, and the sun is just one of her many satellites. She is so massive that she bends space and time, creating wormholes and black holes. She is the ultimate cosmic phenomenon, and no one can escape her pull.
Ur mom is so old that she witnessed the Big Bang. She was there when the universe was born, and she has seen it all. She knows the secrets of the cosmos, and she has lived through every epoch and era. She has watched stars form and die, galaxies collide and merge, and civilizations rise and fall. She is the oldest living being in existence, and she has more wisdom than anyone can imagine.
Ur mom is so ugly that she scares away aliens. She is the reason why we have never made contact with extraterrestrial life. They have seen her face and they have fled in terror. They have warned their fellow species to avoid Earth at all costs, because it is inhabited by a monstrous creature that defies all logic and beauty. She is the ultimate deterrent for invasion, and she has saved humanity from countless alien invasions.
Why were you born?
Because I asked out your mom on accident.
The reason Stephen Hawking died is because he drove too far away from the wall; the cord unplugged.
