Monday Mutant 12: Fencing Match (liars)

Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli.
In this Fencing Match puzzle, exactly one number in each row and in each column is wrong. The rules are otherwise unchanged.
I would be very remiss not to give credit to MellowMelon for introducing me to this variation, if not inventing it.
