SKY NEWS: Students studying at Pocatello High School in Idaho will be targeted by a promotion for a local pizza shop's 14" one-topping special.

The Molto Caldo Pizzeria advert appears on all test papers, handouts and worksheets.

The promotion reads MOLTO'S PIZZA 14" 1 TOPPING JUST $5 in bright red, 2.5cm-high letters printed along the bottom of every page.

History and economics teacher Jeb Harrison dreamed up the scheme.

He believes the school will benefit from more than just a slice of the profits from the deal.

"I just wanted to find a way to save money," Mr Harrison said.

Signs around the school already remind the staff to switch off the lights to save on the electricity bills.

Mr Harrison's superiors were not instantly taken by the take-away adverts though.

But the enterprising teacher explained the advertisements could help illuminate such topics as the Great Depression.
