Blue, Green, Red and Purple: Derailleur
A derailleur is a gear-changing mechanism on a bicycle - and that's all you need to know about biking to enjoy this sprightly limerick by Betty Collins.
A bushwhacked old dame from Australia
Wrote verse that was mostly a failure
Til one day she cried halt
This is hardly my fault
It’s too hard to keep rhyme and rhythm and metre all going like a bicycle using derailleur
