There are a few dolphin trainers out there Otis !!
A favourite is to say 'I`m a Pilot' as no one ever believes it !
Was introduced to a friend of a friend who proceeded to ask me all sorts of complicated flying questions which were clearly relevant to his type eg What`s the Vat for a Cessna Blah Irrelevant Blah in an attempt to oust me as an imposter !!
Maybe I really don`t look like Tom Cruise after all . .. . .
Lighthouse painter, grouse beater and cake decorator all work well !
