A spray per day

Last weekend I was cleaning out the storage area under the bathroom sink, and found an almost-empty spray bottle.  After I had emptied it, I set it aside to put into the recycling bin. Then something that was printed on the backside of the container caught my eye.

 If it might touch your bum, we want it to be really clean. 

a spray per day keeps the scrubbing away

See the little drawing of a bum? How cute! But a bit puzzling. You see, the bottle had contained shower spray; you know, the stuff you spray on your walls after showering. It magically removes soap scum so you don't need to scrub the walls. But how does a bum come in contact with shower walls? My shower is roomy enough that I rarely, if ever, find my bum in contact with a wall. Maybe they meant for showers that come with built-in seats. Or maybe for those folks who shower with a friend, wall-bum contact is a lot more common.

You know, this might be useful to spray our implements with after use, so that they're squeaky clean. After all, if it touches my bum, I want it to be really clean.
