I honestly don't get it. Suicide isn't funny, especially over stupid stuff like this. I know the artist wasn't poking fun at suicide victims, but the fact that this has become a motif you see in humor still really rubs me raw from time to time. I actually wouldn't mind it so much if it was well-done and used for good effect. But the flippant, careless way suicide is used, in particular suicide by hanging, and in particular on a site many people go to for light-hearted fun, it just seems very inappropriate.
I reallly wish people would grasp the fact that for many of us, this isn't really a laughing matter.
