Astronaut's Parking Spot

Listen here, you smooth-brained ape. You thought this up, which means your brain is smoother than a freshly polished bowling ball. The joke is a pun, get it? Astronauts use spaceships. Meteors are like space rocks. “Parking meteor” sounds like “parking meter.” So, the joke is that an astronaut would park their spaceship at a parking meteor, a play on words combining "parking meter" and "meteor".
