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.
