Leunig says on the matter...
A woman needs a man like a fish needs a bicycle
A man needs a sushi when a woman is an icicle
A man needs a car to zip across town
To order a tuna and gobble it down
The tuna needs a car to be partially banned
And bicycle re-introduced to the land
A person would need to be radically pushy
To pedal for miles in the rain for a sushi
Better to stay home with noodles for dinner
The man and the tuna would both be the winner
The world needs to get itself out of a pickle
A woman needs a man like a fish needs a bicycle
