How to Avoid Monkey Butt?

I saw this when I
was at a hardware store in Bellingham, Washington.  I don’t know exactly
what a monkey-butt is or what it has to do with shampoo and body wash,
but the packaging is pretty cool looking…… I don’t think I’d be
enticed to buy it though!! Taken on my iPhone because that’s all I had
on me at the time.
