Chain Mail Letter - S2.E9

When Flicker neglects to mail a chain letter, the curse unleashes itself on Sir Loungealot, who is suddenly overcome with a bad case of the hiccups. With no other resources at hand, Flicker goes to Merle the Wizard, who tells the Squire the cure for Loungealot can be found inside Geoffrey's castle. Now it's the knights who must infiltrate Threadbare Castle without Geoffrey's knowledge.
