Why are quantum physicists so poor at sex? -- Because when they find the position, they can't find the momentum, and when they have the momentum, they can't find the position.
A drunk walks out of a bar late at night and see's a nun walking past on the footpath. He utters something hateful to himself as he begins running building momentum before launching himself at the nun catching her with a massive superman punch to the back of the head knocking her tumbling brutally to the pavement. He proceeded with a swift kicking to the nuns ribs and spine before grabbing the nun by the scruff of her habbit and lifting her limp to her feet til face to face. Looking the nun dead in her eyes with menace the drunk victoriously growled. Your not so bloody tough tonight are ya Batman.
Why did Princess Di cross the road? Momentum.
