What did you just say?

Yesterday the boys and I were in the grocery store. To help them not be bored, they each brought an action figure. I turned away from them to get something of the shelf and I hear Micah say, "Hey, let go of my testicles! Let go of my testicles!" It was really loud so I know I was not the only one who heard. I turn around and ask Micah, "What did you just say?" And he said, "Testicles. You know Mom, like on a octopus!"

I replied in a quieter voice, "I think you mean tenticles."

"Oh!" he said.

I was pretty embarrassed...
