Ceiling The Deal On Stupidity

I’m home with my teenage son, who is snacking on some Doritos. Mid-sentence, he goes:

Son: “Oww!”

Me: “What?”

Son: “I ate down on a Dorito that was standing up. It cut the top of my mouth.”

Me: “Well… chew slower then.”

Son: “I think I taste blood.”

Me: “Lemme see.”

He opens his mouth.

Me: “Hmm, I don’t see a cut or anything. It was on the roof of your mouth, right?”

Son: “Ceiling.”

Me: “Huh?”

Son: “The ceiling of my mouth.”

Me: “The top part of your mouth is called the roof.”

Son: “Why? It’s a ceiling.”

Me: “I don’t know why, it just is.”

Son: “Well, that’s stupid.”

Me: “Almost as stupid as being injured by a Dorito.”

Son: “They’re spicy!”
