“Naked Lunch” just doesn’t sound appetizing to some people. A sandwich called the Skinny Dip, featuring sliced prime rib in a baguette, has been offered free of charge to anyone willing to plunge naked from The Black Frog Restaurant’s dock into a lake. Since the free-sandwich offer was introduced three years ago in Greenville, Maine, owner Leigh Turner found plenty of takers. “We’ve had two or three a week,” he said.

But the promotion is running into trouble: A patron apparently suggested to selectmen that the activity be banned. Turner said he would remove the free-lunch offer if local officials order him to do so. The skinny dip was typically done at night, no frontal nudity was exposed to customers and a towel was readily available, Turner said.
