I well remember a fellow rigger on second line at Cranwell (JPs) being known as "Punkah Wallah" ! It owed nothing to his obvious "brush of the tarbrush", but to the fact that he had seriously cocked up the replacement of the "Punkah louvre" on the pilots side during servicing. I've no doubt that many, seeing the man and hearing the moniker might suspect racist innuendo, not so, simply extracting the urine for a job badly done.
