make whale's sound on the guitar

hey guys
i have been playing wierd sounds on the guitar for a long time now so let me share one small tick with you
to get a sound like a whale just do this
connect your wah pedal completely other way round ie. input in amp socket and vice-versa and now try pushing the pedal
up and down you will get a dolphin like or a whale like cry
hope you like it
