Sounds like Terry Hobbs - God rest his little cotton socks. If he did not say fook and bloody in the last six words you were not listening. And Monty his No2 was so mild mannered and quietly spoken - even when the following happened.
Me "Two gudgeon pin circlips please"
Monty "What for?"
Me "To stop the gudgeon pin coming out of the piston"
Monty "Yup, but what engine?"
