Male aggression over super-masculine rivals

Remember this incident?

BOP!
British Deputy Prime Minister "Two Jags" John Prescott twats a mullet wearing rival.
THWOCK!
Mullet stumbles; Alpha Male 2J goes for an ear box.
WHUMP!
The males go down, entwined in their primeval struggle.

Well they do say a leopard never changes its spots. At least we can now say old Two Jags is true to form now we know that men become jealous of other dominant-looking males when their partners are at their most fertile.

Not that anyone is drawing conclusions about Mrs P's physical condition at the time, but maybe she wasn't rutting, and the secret mistress was. She did, after all, have a fiance (was he a mullet wearer?).
