Who would win in a fight between Nicholson and Ledger?

Ledger hands down. Unless it was a full moon, then Nicholson. If it happened during a solar eclipse, then it would be a tie unless it was a Wednesday during the months of April, June, November and February -- in which case Nicholson has the edge. If however it is a leap year, then its Ledger all day everyday . No one would win on a Mother's Day, Valentines Day or Christmas.
