Following his upset victory over Thomas Dewey in the 1948 presidential election, Harry Truman posed for a classic photograph: Truman is seen holding up an early edition of the Chicago Tribune bearing the premature headline, "DEWEY DEFEATS TRUMAN."

In 1992, Bill Clinton tried to recreate that magic moment during his own presidential campaign -- by holding up a copy of The Weekly World News. Its front page story? The fickle space alien who had once supported George W. Bush (and then Ross Perot) had finally decided to start backing Clinton.

[During the 1948 presidential election, Truman conducted a thirty-five-day, 31,000 mile "whistlestop" campaign during which he delivered 356 speeches.]
