An interesting tidbit from the most recent season of Mad Men (the critically acclaimed drama series about Madison Avenue advertising execs in the early 1960's) was the depiction of Conrad Hilton as seriously interested in putting a hotel on the moon. I don't if this is historically accurate, but it was completely believable. It made for a wonderful moment wherein our heroes, having delivered an impressive pitch to Hilton touting his hotel chain's international cred, are completely deflated when the magnate icily demands to know what happened to the moon.

I ask for the moon and you give me this?

They thought he was being metaphorical about thinking big or something. He wasn't.

He wanted to put a hotel on the moon.

Maybe he was a little eccentric, or maybe he was just a bit ahead of his time.
