A master of the gondola,
Was furious.
Someone had double parked a non-dola.
The inconvenient canals of Venice,
Becoming even more so.
He rammed into this vile contraption,
Clambered over some tourists,
And boarded the unsightly vessel.
Released the moorings,
And set it free down stream (I think).
As he passed by he shouted incomprehensible abuse into the air (because it was Italian)
And threw in a note informing the owner they'd disgraced their family.
