What Are They Putting in Soap These Days?

Everybody knows that when a child says an inappropriate word that means his or her tongue is dirty and needs to be washed with soap. But, since the words have never been very serious or frequent we decided to wait to do that until our son reached the age of four. Surely, having soap rubbed on his tongue would be a strong enough reminder that he should never use those words. So these past few days I've dealt with my son's use of inappropriate words (very infrequent use, I might add) by rubbing bar soap on his tongue. He willingly submitted to the punishment--I mean "solution" to the problem of a dirty tongue--probably thinking that anything was preferable to a boring, long, and repetitive daddy lecture. I rubbed the soap on his tongue. He tasted it. He looked up at me again, un-phased, and said, "It doesn't taste like anything." Then he tasted it again. Wait a minute! When my parents tried it on me the soap was disgusting. That was only a few years ago, or maybe 20. I wouldn't be surprised if soap companies were trying to make their soaps even more attractive by making them tasteless. Thinking that maybe I didn't rub enough soap on his tongue, I did it again until the soap bubbled up and coated his tongue. He tasted it again. Nothing. I was stumped. Was he serious or just beating me at my own game? Maybe both. Now I'm half tempted to taste soap before I use it on him. Maybe that was his plan all along.
