Lyric Writing, Elementary
An early work from self-styled Tim-Rice-of-the-playground Colin Clifford, about his good friend Colin Black:

Colin Black, Colin Black, Went to Vietnam and back, with a knick knack paddywhack and napalm up his bum, came home mad and killed his mum.

Colin Black didn't go to Vietnam, and remains innocent of matricide.

A friend and I once wrote an epic song (numerous sheets of A4 in length) about our classmate Beaky, who was, shall we say, a little odd. I don't remember all of it now, but I do remember frequent use of the word "reeky", and the fact that my mum joined in and even contributed the final line.
