This weekend Paris decided to watch Finding Nemo. She's been watching this moving since she was tiny so we thought nothing of it. I little while later we hear squeals of laughter and our precious daughter repeating over and over "Nemo touched the butt!" We couldn't help but laugh. It took her 6 year sof life to discover that "Nemo touched the butt" (which is actually a boat in case you haven't seen the film) was funny. I'm going to go with peer influence in making a previously innocuous (sp?) statement the joke of the century.
I have to also say that this is one area we've done pretty good with as parents. We have a "no buts" rule in our house. Your "butt" is to be referred to with other terms like hiney, caboose, rear end, bottom, and on rare crass occasions - booty. And if a child in our house ever begins a response with "But...." - well, that's a straight to the corner offense. The rule is simple - No Buts.
Sadly the "no whining" rule has not been as effective.
