Or a dark sense of humor. I do have a dark sense of humor myself and can and have laughed at moments that are supposed to be sad, poking fun at them. I don't do this all the time, and it's usually only when I'm in a certain mood. I tend to keep it to myself, or share it with my brother. And the stuff I tend to poke fun at is usually fictional (as in not canon) anyway.
But yes, I agree with F-14 Ace. Just ignore that guy who made the video.
