I thought this little poem by Michael Leunig was appropriate, Hargs!

Jet-ski person, selfish fink,
May your silly jet-ski sink.
May you hit a pile of rocks,
Oh hoonish, summer coastal pox.
Noisy smoking dickheadfoll,
On your loathsome leisure tool.
Give us all a jolly lark
And sink beside a hungry shark.
Scream as in its fangs you go,
Your last attention-seeking show.
While on the beach we all join in,
With "three cheers for the dorsal fin!"
