when I was growing up my dad used to make this blender stuff every morning, we called it either "the concoction" or "glop."
it was roughly the consistancy of wet concrete, it consisted of lecithin, dry milk, water, frozen bananas, frozen strawberries, brewer's yeast... and some other shit that I don't recall.
he went through man a blender b/c of that stuff burning out the moters.
he finally found one that they guarenteed and if you broke it, all you had to do was put it in the box with the receipt and a note explaining what you were doing when it broke.
this gave me endless amusement and I was always trying to figure out the most interesting way of breaking them and sending them back before they questioned it - I wanted to blend a brick, or concrete, or just throw it and the box down a couple of flights of stairs...
