I wrote this for a college course.  The assignment was to write a poem in this format about a teacher (past or present) that really inspired me, so I chose my jazz band instructor.
The format I used was very specific:
Title is the name of the subject tying into the first line, first word of which being a verb.
The second line describes a common outfit the teacher wore.
The third and fourth lines summarize the main idea of why the teacher is appreciated.
