Mr. Quidworth is a supporting character in Escape from Monkey Island. He is a short man who runs the Second Bank of Lucre on Lucre Island. He lets Guybrush into the bank's vault upon seeing the Gubernatorial Seal of Mêlée Island, which allows him to gather the contents of Horatio Torquemeda Marley's safe-deposit box for his granddaughter Elaine.
Mr. Quidworth confusedly lets a second Guybrush into the vault; this turns out to be Pegnose Pete, who robs the bank. Mr. Quidworth is forced to shut down the bank for investigation, and fires Brittany the bank teller.
