"You've got to remember that the Trunchbull once threw the hammer for Britain in the Olympics so she's very proud of her right arm."

Hammer throwing is an athletic event in which the athlete throws a heavy metal ball attached to a wire and a handle. The men's hammer typically weighs 16 lbs (7.257 kg) and the women's weighs 8.82 lbs (4kg). The athlete swings the hammer above his or her head in a circular motion, picking up speed by turning in a circle a few times before throwing it. 

Men have been able to throw the hammer in the Olympics since the early 1900s, but the women's event was not introduced until the 2000 Summer Olympics in Sydney, Australia.

The hammer throw is also a very popular part of the Scottish Highland Games.
