To whom should the judge grant the prize?

Question

John, Paul, George, and Ringo all enter a race, but there is nobody at the finish line to judge the ending. When the judge finally shows up to award the prize for coming in first, these are the statements the four of them make:

John: I was neither first nor last.
Paul: I did not finish last.
George: I won the race!
Ringo: I came in last.

The judge starts to hand George the prize, when Yoko, who was watching the race, says, "Exactly one of these four is lying."

To whom should the judge grant the prize?

Answer 1

Only when we take George's statement and assume it to be false every other statements holds true. So George is lying and Paul is the real winner.
