Listening to edits and staying entertained

For a broadcasting school production class instructor, it must get monotonous to hear hundreds of essentially identical student-edited versions of Pink Floyd's "Money" and Queen's "Bohemian Rhapsody."  It's no wonder, then, that one instructor whom I asked to listen to my condensed version of Depeche Mode's "Policy Of Truth" started my tape and drummed along on a desk with it, using two pencils, the entire time.  At the end of the tune, he asked, "Did the song time out OK?"  I said it did, and he marked down 10 out of 10 points for my rendition.  It isn't often that a school project elicits three minutes of drumming from the person grading it.
