See where Joe is pointing?
It may not look like it, but that is Joe's Dad's tickle spot.
You see, Joe and his Dad have this routine
where Dan asks Joe to point to his tickle spot
and that tickle spot isn't on Dan, it is on Joe
when he touches that spot
he giggles uncontrollably.
And when Joe laughs, Dad laughs, it is hard to avoid.
I don't suppose it tickles that much, but the idea does make him laugh.
A special memory, for sure.
