He was in the back seat and all of a sudden said, " Hey Mom did you know that George Washington didn't have real teeth. He had pretend teeth but they fell out all of the time. Also I don't think they were that comfortable." We talked about George Washington for a while and then I asked him if he knew anything about Thomas Jefferson or any other presidents. He said, "Mom I'm in kindergarten I cant know everything about all the presidents. That's for when I'm in like 7th grade." I definitely got a laugh out of that response.
I was curious about the George Washington tooth fact so I looked it up and sure enough he only had one real tooth when he was elected President. He spent thousands on dentures and most caused him significant pain.
