Why are they called Milk Duds?

"In 1926, F. Hoffman & Company of Chicago set out to make perfectly round chocolate-covered caramels. The manufacturing equipment didn’t quite cooperate, however, and what came out were oval-shaped candies. A worker pronounced them “duds,” but everyone agreed they still tasted good, so the company kept producing them under the playful name. Two years later, the Holloway Company bought out Hoffman and brought Milk Duds to the masses."
