"Red Night" joke

Ahhh -- the good ole days when Ronnie was in office:

Presidential Aide - Mr. Reagan!. Mr Reagan Sir!!! The Russians have just landed on the Moon! And they've started to paint it red! What shall we do?

Ronnie - Come back when they've finished, son.

P.A. [later] - Mr. Reagan Sir. The Russians have painted a quarter of the moon red!

Ronnie - Don't worry about it, son. Tell me when they've finished.

P.A. [still later] - Mr. Reagan Sir. The Russians have now painted half the moon red! Aren't you going to do anything?

Ronnie - Nope, not yet.

P.A. [still later and even more anxious] - Mr. Reagan Sir. The Russians have now painted THREE-QUARTERS of the moon red! Can we bomb them, Sir? Please, Sir?

Ronnie - [ as before ]

P.A. - Mr Reagan. They've painted the WHOLE moon red!

Ronnie - OK. Now call NASA, and tell them to get a rocket up there, with plenty of white paint, and paint' Coca-Cola' across it.
