I get why a government or non-profit might want to raise awareness about cancer, but I cannot imagine why they would feel the need to have a mascot for the campaign (especially when the cancer in question is testicular cancer). It does make the campaign memorable though, so maybe that’s the reason.
In an unbelievable article called “Mr. Balls, aka ‘Senhor Testiculo,’ goes to bat for cancer research,” the NY Daily News writes that a Brazilian testicular cancer awareness group that has created a mascot that is a “wide-eyed, dual-toothed, rosy-cheeked, mole-sporting scrotum that will cause a lifetime of nightmares for anyone who lays eyes on him.” I would second that last sentiment. Here is Senhor Testiculo in all his glory. Who are the parents that think it’s a good idea to let their kids take pictures with the mascot. I found clowns scary as a kid–god knows what kind of therapy I would have needed if I had confronted Mr. Balls on the street.
Word of warning: while at least some Brazilian parents would beg to disagree, I would argue that the following photos are NSFW.
