Many, many moons ago I used to work as a passenger boat captain, and I was given a private job at Henley Management College. Easy job, pick up some people, drive them around a bit whilst they got drunk, and get them back to Henley Management College without killing them. Bobby was on board and asked to use the PA system, then proceeded to crack jokes for about ten minutes. He also encouraged the guests to put their hands in their pockets to sort me and my crew out with some tips, so I can't fault him.
