Old Joe is a criminal in A Christmas Carol who buys stolen items such as the clothes from the dead Scrooge, to sell at a later date.
During Ebenezer Scrooge's future, his former maid is seen selling his clothing to a fence named Old Joe. During this, Mrs Dibler and Old Joe share some banter about a mysterious death on Christmas Day, and that they would somehow get profit because of this death. Scrooge, now noticing all of his stolen goods, yells to his former maid that she is fired, but because The Ghost of Christmas Yet To Come shrunk him earlier, she can't hear or see him. But then Old Joe is seen with a fire poker swung in the direction of Scrooge. The fire poker was actually aimed at a nearby rat. This starts a three way chase between Old Joe, the rat and Scrooge.
