Can you see how he is laughing? Like he knows something hysterical, but isn't sharing with anyone?  He does this from time to time and it just cracks me up.  The laughter is contagious.  Even better is he knows when to do it sometimes.

Personally I found his pj arrangement quite funny.  Since he will not stay under the covers I didn't want him to sleep in shorts just yet.  It has been warm here lately, but it does cool off at night.  So when he insisted on wearing Spongebob to bed I said he could, but with pants (the set has shorts).  So he decided it went well with dinosaur pants.  And to him it makes perfect sense - in fact since then he has asked for the combo again.  The rest of us, well not quite as much.  Daddy actually did a double take when he saw it.  Daddy isn't always up on fashion, but he was pretty sure that wasn't right.  But for our little man it is perfect.  :)  And proof that he has indeed grown in the last year (like I didn't know that already).  (The shirt used to be loose and adequately cover the belly.)
