This scar

This scar on my right arm
Is not from a fearsome battle,
Nor from a sporting accident,
Not even from racing on a circuit
Or from a marshal bout in a Dojo.

This scar on my right arm
Is not from an infamous fight
With a drunken clod at a pub,
Or from a fight at match,
Or from a clash with the police.

This scar on my right arm is the result
Of a momentary laps of concentration
While getting a pizza out of the oven.
