'B' block had three floors and two stairwells at either end ot the building. Although you couldn't get more than about three metres before hitting a right angle, you could - albeit briefly - slide down the bannisters.

One afternoon Richard Randall started his trademark descent from the top floor. Something clearly went awry, because instead of enjoying a few seconds of sliding bliss, he plummeted to the floor at bottom of the stairwell.

As a direct consequence of the event, slightly weedy looking 'safety bannisters' were welded onto all bannisters in the school, bringing their height to about 2 metres - far too high to slide down. These were immediately christened 'Randallbars'.
