It's thigh time.... the seat of advertising on a park bench-New Zealand

Beware of the park bench this summer

A New Zealand ad firm has come up with the ultimate summer advertising - imprinting messages on the back of people's thighs.

DDB Auckland came up with the campaign for Superette, an Auckland boutique chain, who wanted to promote a shorts sale.

"We put indented plates on bus stop, mall, and park benches, so that when people sat down, the message was imprinted on their thighs," the agency said.

"This meant that as well as having branded seats, a veritable army of free media was created, with thousands of imprints being created and lasting up to an hour."
