They are well known for getting lost, even when the GPS is working, and have a reputation of being very full of themselves. Their navigational skills and hubris are therefore very highly regarded as a matter of jokes. For instance, there is the famous joke about a radio conversation between an American aircraft carrier ordering an unknown radar contact to change course to get out of the carrier’s way, using increasingly severe threats, as the order is refused repeatedly, only for the unknown contact identifying itself as a lighthouse in the end.

Edit: Jokes are already starting, like the German equivalent of The Onion running a story about an American aircaft carrier showing up in Germany on the Elbe river, looking for Greenland, because there is a small village bearing the same name there
