singing clothing?

Year ago we had a Director who was a dignified portly gentleman. He was walking along the corridor when he suddenly clicked his ankle bones together & his Christmas socks gave forth with a very tinny version of Jingle Bells ...

He continued walking along in his portly gentleman mode as if nothing had happened.

He was also know to stop if he saw an unattended computer & send himself a rude email! Then call in the disobedient employee who had left classified Govt info open to the unauthorised gaze.
