I thought I remembered something about the UK's Mars Bar being like the US's Milky Way. A brief jaunt to wikipedia,

The Mars bar was first manufactured in Slough, England, in 1932 by Forrest Mars Sr., son of American candy maker Frank C. Mars. He modelled the Mars bar after his father's Milky Way bar, which was already popular in the US, adjusting the recipe to better suit European tastes. He had a staff of twelve people, and originally advertised it as using Cadbury's chocolate couverture. As a result, the "British" Mars bar (also labelled the "European", "Global" or "Original" Mars bar) is considered to be a version of the American Milky Way bar, with only a slightly sweeter taste.
