Sweetest little fellow,
Everybody knows.
Don't know what to call him,
but we think he's one of those.
When running for a tram-car,
or a trolley bus.
He trips so light and dainty,
that we think he's one of us.

Tune:- "Mighty like a rose"

Don't know the origins of this, or any other verses, but seem to have known this bit forever.
