Maine ? “Naked Lunch” just doesn’t sound appetizing to some people.

A sandwich called the Skinny Dip, featuring sliced prime rib in a baguette roll, 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, owner Leigh Turner has found plenty of takers. “We’ve had two or three a week,” he said.

But now the promotion is running into trouble: A patron apparently suggested to selectmen that the activity be banned.

The naked lunch issue surfaced this week when Town Manager John Simko presented the Black Frog’s application to renew its liquor license. Simko said he had been approached about the nudity and suggested that Police Chief Scott MacMaster speak to the owner.

Turner did not attend the selectmen’s meeting, but said he would remove the free lunch offer if asked to do so.
