With the completion of the transnational Øresund Bridge in 2000, Copenhagen has become the center of the increasingly integrating Øresund Region. Within this region, Copenhagen and the Swedish city of Malmö are growing into a combined metropolitan area. Copenhagen is situated on the islands of Zealand and Amager.

In "Mr. and Mrs. Stewie", stewie and Penelope play a variation of "truth or dare", drawing locations, disasters and themes to wreck havoc. Stewie draws Copenhagen by tidal wave with the theme of The Roaring 20's" and successfully involves flappers on surfboards doing The Charlston along with the tidal wave.
