A small blue plastic hammer of
approximately 6 inches in length, owned by Mary, used for certain offensive purposes. Unlike Maxwell's famous Silver Hammer, Mary's Plastic Hammer is incapable of killing anyone, or even doing any
significant damage. Instead, any individual who is hit
on the head with the hammer is immediately turned into a nerd upon impact.
Little Mary had been playing with
The Plastic Hammer for an hour or so when she became bored and tossed it behind her back, hitting Maxwell, her
older brother,
in the head and turning him into a nerd for the rest of his life.
