I have been laughing since I read this post/question at the picture. I don't know what it is but maybe the macho image and the cheap necklace or what looks to me like an all-in-one that he is wearing but there is something wrong about the look. Yeah, maybe the necklace, No, maybe the maniacal look in the eyes.
Maybe the singlet straps are too thin - maybe it's a ladies singlet.
This is very, very funny to me
