Task: Question Answering
Input (English): Passage: That lovable know-it-all knucklehead Ernest P. Worrell, who is working as a janitor at a local college, meets a history professor named Dr. Abner Melon. After discovering an antique metal plate near a construction site, Ernest shows it to Dr. Melon who believes that it came from a giant Revolutionary War cannon called "Goliath", (named after the legendary biblical giant). Dr. Melon had previously been ridiculed by his peers for theorizing that the real Crown Jewels of England were stolen during the Revolutionary War and were actually hidden inside the long-lost cannon. 
They begin to search for the artifact near the construction site and eventually locate it inside an abandoned mine. They are ambushed by historical antiquity collector and Dr. Melon's colleague Dr. Glencliff whom they then lead on an action-packed chase through the countryside. Things become more complicated for them when British authorities hear about the incident and send a team of secret agents after them to retrieve the jewels. Dr. Melon's wife, Nan, on the other hand is only after him and Ernest for the jewels. While everyone is hot on their trail, Ernest develops a deep friendship with Dr. Melon. After crashing the cannon into a forest, Ernest locates the jewels, not in its barrel as the legend describes but in the gunpowder kegs. After putting the crown on his head, he finds himself unable to get it off. Dr. Glencliff shows up, abducts him, and takes him to his clinic in an attempt to surgically remove it and kill him at the same time. Dr. Melon meets up with Nan and convinces her to help him save Ernest. 
Question: What are the full names of the people who lead Dr. Glencliff on a chase through the countryside?
Output (English): Ernest P. Worrell.
