Musical sine wave
During assembly we were ordered to sing hymns, but since everyone hates singing, especially hymns, Mr Duckworth walked up and down the aisle that separated two blocks of chairs to ensure that everyone was singingk, and enjoying themselves.
We were later told by the physics teacher that people only sang when Mr Duckworh passed them, thereby creating a "musical sine wave" as he walked up and down the aisle, growing increasingly angry at the fact no-one was enjoying singing hymns.
