The First Law of Child Conversations

Having spent the past few days riding for extended periods of time with the kids in a car, I’ve decided to propose The First Law of Child Conversations:

As the length of a conversation between children increases, the probability that one of the following words (or a variant thereof) will be used approaches 1: poop, butt, fart, burp, diarrhea, pee.

Also, I propose the following corollary:

The time before one of these words is used decreases exponentially for each additional child in the conversation.

I, personally, have witnessed a gathering with as few as 6 children where a conversation started with the comment “I think the dog farted.” I’ll also note there was no dog around.
