Is another German expression meaning to be lucky when it was not to be expected (or deserved). It came to my mind when I saw the picture above in the National Geographic POD (Picture of the Day) gadget in my iGoogle page. It also gives me the opportunity to write about the fantastic photos on http://photography.nationalgeographic.com/; most (all?) of them downloadable in high resolution as wallpaper.
More than just Schwein gehabt.
