For me the worse was Jerry's monster with the spikes around the mouth that got him eliminated. Heck, even Sue's final makeup was at least beautiful and well-done, he was a laughing stock in his final makeup.
And as far as "Can't do the prosthetics" - I should clarify: I do not know how to make the molds to run foam/latex (or run foam/latex for that matter). I can design and make the faceplate out of clay on a form though. As a jewelrymaker and sewer; however, I can fabricate like no one's business.
