The ironmonger

Dad's trade was ironmongery.

He sold fingerplates to restaurants.
He sold hammers to actors.
He sold mitre blocks to bishops.
He sold saws to dermatologists.
He sold pans to critics.
He sold bolts to tailors.
He sold locks to hairdressers
and peelers to policemen.
He sold clocks to town halls.
He sold cups to footballers
and catches to cricketers.
He sold hooks to songwriters
and kettles to timpanists.
He sold doormats to husbands.
He sold planes to airlines.
He sold screws to prisons.

More of an irony-monger really.
