In the movie High Time (Bing Crosby - 1960). The freshman have completed
their bonfire and the upperclassmen are checking to make sure that it is
high enough. The upperclassmen are using a surveyor's level and a tape.
The measure the distance, get the angle, and then the upperclassman
pulls out a slide rule to calculate the height. It looks like a K&E
duplex.
