Sure, it's strange to have cube-shaped watermelons, but have you seen a pyramidal one?  How about cucumbers  that slices into heart or star shaped bits.  Link.

Have you heard of the Miracle Berry (also known as Magic Berry)?  It's a fruit with Miraculin, a type of protein that when it binds to the tongue's taste buds causes subsequently eaten sour or bitter food to taste sweet.  Some say it made sour lime taste like limeade.  Link.

Going Bananas?  Or should I say going, going, gone bananas?  Now there's nothing unusual about this fruit and people haven't shaped them into bulbous balloon animals (not yet anyways).  But apparently, this fourth largest harvested crop in the world is in danger of extinction, the common Cavendish variety that is.  Link.

Lastly, if you don't like eating fruits, maybe you could wear them... as earrings!  Link.

This truly is a weird wonderful world.
