Naked Sleeper

Lately, Max has been asking to sleep naked.  I let him try and he ends up getting up 30 minutes later to put on his pajamas.  In this photo, he put his pajama bottoms on and fell asleep with no shirt.

I'm not sure what to make of a 4 year old trying to sleep naked...and then being unable.  It probably means exactly NOTHING, but it sure cracks me up...and then gives me pause...hmmmmmmmmmm?

Any similar stories out there?
