when i was about 5 or 6 my mum always told me to be very careful not to swallow any watermellon seeds because if i did a watermellon would start growing in my tummy and no body would ever be able to get it out. i believed this because my older sister told me our dad (who had a very big belly) had swallowed some seeds and he had a watermellon in his tummy... he still has a big belly maybe its still in there.
