Oh right, those "depraved" salaryman punters are completely naked with their dangly bits hanging out.

("Depraved" as in throwing away all sense of decency to go bet like crazy in races, with the clothes/nudity being used as a visual metaphor. Nothing lewd is involved and those guys are drawn with simplified Doraemon/Crayon Shin-chan style comedic genitals, if they're drawn at all.)
