"...We haven't been on the moon since December 11th, 1972...."
Make that December 14th, 1972 when Gene Cernan and Jack Schmitt lifted off from Taurus-Littrow. Anyway, Cernan has said that his record for being the last one to set foot on the moon is one that he'd gladly relinquish. He has stated many times that he wonders when that will be.
