I used to believe that the cattails (bullrushes) that grew around my grandma's house were liable to explode like land mines if I touched them. This was because my grandma would use them to decorate during the fall and to deter me from touching them she came up with a story about them exploding. I was too afraid to ever try to touch on to figure out for myself.
