Another cheery list from the crew at Cracked: five successful companies with Nazi skeletons in their closet. Even if you already know the history, you should appreciate the exposition:
[T]he Beetle is perhaps one of the most misconstrued cars in history. People look at its rounded shape and anthropomorphic face and instantly think of love, peace and smoking massive quantities of pot. But it was really designed as a tool for everyday life in the always-cheerful Third Reich. Give credit to [Ferdinand] Porsche for designing a car so impossibly cute that we forget it was built by diseased slaves in some dark, dank factory in Stuttgart, Germany.
Whole thing here.
