Male Genital Mutilation is funny, amirite?
I think things like de ballen (google it), and some other penis cutting pictures found on shock sites are funny.
It's not so much the actual cutting, but the fact that these males are so stupid as to do that (unless they really want to change genders, that is, and even then it's still funny). And thinking about other males' reactions to the pictures/videos makes me laugh, too.
What's wrong with these people.
