My sister told me that the pips and liquid inside tomatoes were poisonous, and that you were only supposed to eat the skin. I think this was because she hated tomatoes and she wanted me to dislike them too. I don't remember when I was disabused of this belief, but it must have happened, because the slimy bit in teh middle is my favourite part now.
