Hanged by his own Petard

Mr. Chu was caught half-in and half-out of someone else's room after his latest theft. The poles on his wheelchair got stuck, and the staff left him there for at least an hour. There was much merriment in the nursing home, even among those whose life's work is helping others. It was like watching a beetle on its back without righting it. I murmured, "Crime does not pay" as I walked by, and he ignored me. A little schadenfreude, anyone?
