Cut the crap, we all know we read those on the toilet.
I dunno, it's a pretty complicated process. Do I lather once? Twice?
Three times? THE POSSIBILITIES ARE ENDLESS.
But what if you forget to rinse? What if you don't lather? And oh, the terror, what if you forget to repeat?
Well say a black boy is growing his hair out for the first time, and he's used to just letting water run over his (nonsexual)head in the shower. But now he has this huge afro, and just doing that won't clean it. So, he buys some shampoo, reads the directions, and uses it.
I'm laughing at what that would sound like with the (nonsexual) part. XD
