what's in his underwear?

My twins were helping me put clothes in the washing machine yesterday. I was explaining to them how we sort clothes by colour, and how I have to check the clothes for stains, and check the pockets for "treasures", before I put them in the wash. So they were carefully examining each piece of clothing for signs of stains and checking pockets, when suddenly Taylor held up a pair of Mike's boxer-briefs and said "Look, Daddy has a pocket in the front of his underwear!"
