Update to Mr. Pants-Less

So, last night Monkey decided it was time to try another article of clothing.  He easily put his shirt over his head, struggled a little bit with the arms and voila - topless baby.  I convinced him to put his shirt back on for bed but when I went in to get him this morning he had started the process all over again

And now my baby is running around the house looking like this:

I'm assuming at some point he will get cold and want to put it back on since I've done it twice already and he has undone it.
