When I was about 8 or 9 I asked my brother why there were always big storms at the Cape of Good Hope (I think we had been watching some adventure film about Pirates). He proceeded to give me a long and detailed explanation. Apparently the Atlantic Ocean was actually 32 feet higher than the Pacific Ocean. Where the two Oceans met, this large gap resulted in violent crashing of waves as the waters came together.
Completely plausible and beleived by me for many years.
