I was dealing with a new subcontractor who was about to start a drilling job in a small access tunnel at work and he asked me not to call him this afternoon with a start time as he was attending a funeral. I jokingly replied "I hope he has a confined space permit?" He retorted, "No its a cremation!" Quick as a flash I replied, " I hope he has a hot works permit?!" We somehow got on really well after that and although I didnt stay with the company he still remembers me!
