3. Popcorn!
In Mick Foleys first autobiography, Have a Nice Day: A Tale of Blood and Sweatsocks, the hardcore legend recounts a story whereby a wrestler who was involved in an over the top battle royale was hit with a box of popcorn thrown by a fan. Not only did the wrestler mistake the popcorn hitting him for his opponents attack, he also sold the popcorn box like it was an Andre The Giant clothesline and promptly eliminated himself from the match once it hit him! Obviously, Foley was impressed by this story, as he used a gigantic bag of (already popped) popcorn against The Rock and also against Owen Hart (who, given his reputation as a practical joker is probably the originator of this particularly devastating foreign object).
