Staying on the fruity theme, bananas have a couple of tricks up their sleeve as well. As well as making an excellent food for babies, peeled bananas can be wrapped in cling-film, frozen, then eaten a bit like ice cream!
On a non-edible note - you can also use banana skin to give brown leather footwear an extra shine. Just rub the inside of the banana skin over the shoe, then polish as usual (removing any rogue fruity bits!).
