I saw an episode of Popular Science's Future of, and it had this interesting part about the miracle berry. Turns out the miracle berry makes everything sour or bitter taste amazing and sweet. It also affects other foods... I guess you can eat a miracle berry and then lick a fresh stalk of broccoli and it'll taste like ice cream. And good tasting stuff will basically make you orgasm.
