Here's a curio to be sure - a Homemade Recorder Bagpipe. Makes me think, might there be a historical precedent for such a thing? Think bagpipe, think reeds; but whistle flutes??? It obviously works, so why not?

As for the Whoopee Cushion. These were invented for the sake of pride in Victorian England when those aristocratic gentlemen of the hunt found themselves, for whatever reason, no longer able to let rip. Essentially a prosthetic anus in that respect (however so remote) a chap would maintain his dignity by still being able to oblige with some choice trouser hoorahs.
