My munchkins have dragged random items home, including 8 pounds of fine Taldan chocolate, a stuffed wyvern, and a set of Paracountess Zarta's lingerie.
As a GM, I've let people claim everything from a pet rock (Steve!) to a lock of (chest) hair from Miss Feathers.
Mostly, it's for fun and giggles. Any benefits resulting there are small and entirely up to the GM's discretion (I think the character with the chocolate got +1 diplomacy when consoling an upset woman..)
