Moosylvania
Moosylvania is a fictional island between the U.S. and Canada, in Veronica Lake, a fictional body of water in Rocky and Bullwinkle. Its governor is Bullwinkle J. Moose. The U.S. claims that it is part of Canada, and Canada claims that is part of the U.S. because neither country wants to own it. Bullwinkle vacations in Moosylvania because "after two weeks here, anyplace else feels like Heaven."
