Park in It

Okay, so like, you’re probably one of those types that struggles with simple wordplay. So here's the deal: this joke plays on the double meaning of 'spaceman'. It sounds like 'space, man', you know, like 'hey man' or a request to park in the space. The punchline is that, when you see a spaceman, the answer should sound like you're giving a directive to park in space. Get it, genius?
