Yahoo answers is useless for getting information but sometimes it works for mild humour and/or found poetry. A comic going by the internet handle of Clint Westwood wrote:
There are 17 types of Avocado in London alone – mostly situated in the Borough of Hackney where residents have an Avocada identification competeition every Thursday morning . People are blindfolded , lined up and then pelted with avocadae and must distinguish between various densities , skin crinkliness and of course taste . During the Second World War , when avocados were rationed , they used bananas instead , but , having only one type , this became tedious and they went back to singing songs down the underground . Other options included grapes and stale bread the latter a complete failure .
This could be a very believable piece in a game I once played. You are given a question to answer about a person place or thing and the other players have to say yay or nay to your answer if its believable, and I have won quite often. Fun Pearl, thanks!
