Humor or just handling the situation in a very bad way?

"Oh, and he don't know...
That I dug my key into the side
of his pretty little souped up 4 wheel drive,
carved my name into his leather seats,
I took a Louisville slugger to both headlights,
slashed a hole in all 4 tires...
Maybe next time he'll think before he cheats."
- From the song 'Before He Cheats' by Carrie Underwood

"Humour is the weapon of unarmed people: it helps people who are oppressed to smile at the situation that pains them."
- Simon Wiesenthal

"Through humor, you can soften some of the worst blows that life delivers. And once you find laughter, no matter how painful your situation might be, you can survive it."
- Bill Cosby
