You say potato, I say kartoffel

Just before xmas I was in eh... I actually don't remember the name of the town, just outside Stuttgart, Germany, a beautiful little place whith wineyards stretching in all directions. However, great wine is not all this place has to offer. While vending machines are pretty common around the world, I've never before seen one where you can buy potatoes. Pretty cool... not to mention the word kartoffel! I love it.
