Granted, aliens abduct you and take you to the moon, where they pull out your liquid excretory system (the urine part) and drape it over a crater, forcing you you to painfully urinate before your death, all for their barbaric amusement
Granted, you’re peeing when the moon crashes into earth.
Granted. You are lost on the moon forever trying to look for some urine to take back home
Granted… Nothing sinister is inserted into this wish since just doing as asked is already a terrible situation to be in
Granted. You become an astronaut and make it to the moon. Once there, you and your colleagues bring a dog named “Piss” out of the shuttle and onto the moon. He has his zoomies while you all zoom off of the moon, leaving piss to die. You monsters.
