Obviously there were WMD's on the Moon so we bombed it.
Really what idiot thought it was a good idea and a fine time to say "Hey, Lets blow up the moon and see what happens?", and then someone agreed. That sounds like an idea you would get after a long night of getting high and drinking to much.
High Nasa scientist: "Duuude, what if we. Me and you sent a bomb to the moon.... and it blew up? You think we might find some water?
2nd High Nasa scientists: "Whooa that would be cool! I think I remember someone say we got some bombs in hanger B."
High Nasa scientist: "Ok you go get the bombs and i will go get the rockets, and we will come back here in like an hour. Duuude this is gonna ROOOCCCKKK!!"
2nd High Nasa scientists: "OOOhhh man wait, we should get Jerry to send up his satelite with our rocket at the same time!"
High Nasa scientist: "Your right! cause you know what, then?!!"
Both high scientists after 2 long hits together say: "Then we can put it on YouTube!!!!"
