I remember a tale I overheard my father telling my mother many years ago.....my father was a part time Insurance collector and there was an elderly couple in their 70,s that he collected from...one day the old chap asked if my dad would help him out...my father replied what type of help do you mean the reply was that his wife was feeling frisky and could my dad give the old chap some assistance in climbing up to get his leg over....a bit nonplussed my dad said but if I do how will you dismount..so to speak....to which the chap replied "but you will be coming back next week won,t you"....
