Three special forces guys, one English, one American and one Irishman get captured in Libya by Colonel Gaddafi. Each is given one chance to save their lives, by trying to cross the desert to the border without being caught, in the vehicle of their choice. The Englishman chooses a Rolls Royce, but it quickly becomes stuck in the sand, so he is easily caught and shot.
The American chooses a Humvee, and tears off across the desert. Just before he reaches the border he is hit by a missile from a helicopter gunship, and is killed.
The Irishman chooses a rubber duck toy, and four springs. Gaddafi's troops all laugh at him, and he sets off to cross the desert. Later on he crosses the border to safety, and the confused Gaddafi troops ask him how on earth he evaded capture and certain death. He simply answers Vorsprung Duck Technic.
