Is it normal to think it's so tragic that it becomes funny?
This guy I know offered to donate a kidney to his dying child then found out he's not a match because he's 'unrelated'. Then he had a DNA test done on his other two kids and found out none of them are his. And subsequently his wife divorced him, shacked up with the guy she's been screwing around with and sued him for child support.
It's awful and it ruined his life. But I can't help but think it's kind of funny because it could not have gone any worse than that. The bad luck that he was living a huge lie is so crazy that it's funny to me that it actually happened.
