The proof is in...the laundry!

Yes, this is a picture of underwear ON OUR BLOG.  One of our children doesn't change their underwear frequently enough to my liking...can you identify which child this is?  On this particular day, I took a picture of the underwear data that was collected after completing a load of kids' dryer clothes.  I'm CERTAIN this picture will motivate him to change these hummers more often...
