A moonraker - A moonraker is someone so dumb they’d try to rake the moon’s

A moonraker is someone so dumb they’d try to rake the moon’s reflection in a pond, and then blame the water for their stupidity.

My uncle tried to build a spaceship in his garage, and it looked like a toaster.

My friend thinks the moon is made of cheese, and he eats it for breakfast.

My sister tried to talk to the moon, and now she thinks it’s her ex.
