Burt the Ditchdigger is a character in The Life and Times of Scrooge McDuck. His role in the story is brief, but important.
Burt's boots are covered in dirt due to his job as a ditchdigger. When the young Scrooge McDuck becomes a shoeshine boy, his father Fergus McDuck gives Burt an American ten-cent coin to pay Scrooge after he shines his boots, so when Scrooge gets that useless American coin, he will learn to not be so naive and be inspired to reach the top. After Scrooge passes down shining Burt's dirty boots, he wakes up with the ten-cent coin on his hand. This coin becomes Scrooge's Number One Dime and he learns to be tougher than the toughies and smarter than the smarties, and do it square.
