The shower stall is the last place I'd think of hanging a poster, but this poster is specifically designed for the shower. The reason is simple: when it gets wet, the big-breasted anime girl gets naked. When it's completely dry, she's SFW again, so when your mom comes over and uses your bathroom, you won't be embarrassed by having a naked poster in your bathtub...you'll just have to explain why you have a busty cartoon character poster in there, which might be harder to explain than the nudity. Lastly: am I a pervert to wonder if the bra disappears when you pee on it? I don't want to do it, but in the interest of Science!, somebody might have to try it.
