Caps For Sale

The peddler has a huge stack of caps, balanced carefully on top of his head. Brown caps, blue caps, gray caps, and red caps. But no one wants to buy a cap. So he goes for a walk in the country and takes a nap under a shady tree. When he wakes up, the caps are gone -- al except his own checked one. Where could his caps have disappeared to? And how will he ever get them back?
