Harry Houdini was a magician.
When the sheriff put handcuffs on Maggie, they slipped off her hands, because they were too small. The sheriff then said "It looks like we got a teeny Houdini here." and went for handcuffs for babies.
Houdini also showed The Great Raymondo how to do "The Great Milkcan Escape". He taught Lisa the trick, but she then revealed it to Cregg Demon's son. Before the "World Magic Championship", Cregg Demon said to reporters that he is going to present "The Great Milk Can Escape" and it was Houdini's ghost who told him how in a dream. Before doing the trick, Demon hoped Houdini was watching up there, because he did for Houdini's great-grand niece.
