When I was 12, my older brother was big into army stuff and always drank from a canteen. I went into his room one day and saw the canteen. I stuffed a bunch of ritz crackers in it and poured tabasco sauce in it too, then shook it up and left it there. The next time he took a drink, he spat it out all over! The belief comes in because I just recently told him I had done it (I am 26 now) and for all this time, he thought it had been our younger brother! (Because I would never do something like that...)
