Lemmy Kilmister of Mötorhead may have been known for his hard drinking, but he'll be forever remembered in an ad for a different beverage. Milk.
Just weeks before he died at age 70 from cancer, he shot a TV ad for the Finnish dairy products company Valio. After the rocker's death, Valio ran some of Lemmy's unscripted, improvised material -- which wasn't even part of the ad! -- as a tribute to the heavy metal icon.
