marching band director 

The person in charge of picking music, writing drill, and teaching the band how to march. Can usually be found saying, "One more time!" and then having the band repeat it seven more times. The band director quite often does no dirty work of their own and has the drum major take care of it.

The marching band director could never be trusted when he said "One more time"
