We had to endure a several year stint by a 6′ 4″ Aussie , who was in the geography department. He had to to see England from the Northern Territories , and was, conservatively speaking, barking mad too.
His piece de resistance was using a size 12 plimsoll, which he applied with a run up. Probably makes little difference to the impact but was spectacle and hardly intended to encourage class participation! . Trouble with him was he was completely inconsistent, sometimes he punished, sometimes he didn’t is was like drawing a lottery ticket. He also used to rip unsatisfactory work out of exercise book and , screw it up , and ‘bowl’ it into the waste paper basket.
His main claim to fame was having traveled from Australia on the ‘Canberra’ in the company of the then Australian cricket team , a fact of which he was immensely proud.
