Look at Me, Mommy!!!

What's wrong with this picture?

Luke is about 99.9% potty trained.  We still have an occasional accident but overall he is doing great.  He even wears his underwear to bed - no pull ups.  Paul got tired of taking a perfectly dry pull up off him every morning so we stopped those a couple of months ago.  He is also fairly independent in the restroom.  He can go by himself.  Tonight he was being silly and put his underwear on inside out and backwards.  He has such a funny sense of humor.  He knowingly put them on wrong but acted like it was perfectly normal to have his underwear on that way.  When I started laughing he said "what's wrong mommy, what?" then he broke into hysterical giggles!  That boy is something else!
