It should be noted that while JFK "threw our hats over the wall" and LBJ carried on with that quest for another five years, the plaque on the surface of the moon mentions only Nixon, who had been in office just six months when Apollo 11 touched down. Class act.
In 1986 when the Martian Liberation Organization forcibly seized control of the 11th Annual Boston Science Fiction Marathon over the less than flattering portrayal of the Red Planet by Hollywood, among their demands was that Nixon's name be removed from the moon. This may sound like silly, idle threats from a Marathoid fringe group, but they also demanded that after a decade long absence, red M&Ms be returned to our candy counters. The Mars Candy Company took them seriously enough that within a few months, production of little red friends that melt in our mouths, not in outer space, had resumed. But unfortunately, to the best of our knowledge, Nixon's name remained on the moon and the Orson Welles Cinema was destroyed by fire.
This just in, from the sensor implanted at the base of my skull: The MLO are our friends. Do exactly as they say, and no one will be hurt. Free Mars!
