"Three clicks to what?" the elves ask. 

"Don't you remember.  It's your self-destruct device!" 

"Oh, that thing.  Yeah."  Then, shreiking:  "WE'RE DOOMED!" 

"-- So anyways," the Green Knight, who has been talking through all of this, concludes, "even though you didn't want to hear it, that's who I am and what this is really about." 

"Amazing!" says the voice of Sir Irving through the pipe.  "He claims that he is the long lost head of King Henry, and the one we've got in the wheelbarrow here actually is a pumpkin!" 

"I was beginning to wonder," King Richard says.  "But I didn't want to say anything.  You know how sensitive he was about his looks." 

"And then," Sir Irving continues, "he described how the Headless Ghost of the Castle of Terror picked up his head when it was deposited on the doorstep of the Castle of Terror by that ill-fated firecracker explosion." 

"I knew all of this," Rocky says.  "That's why I went on a quest to find a knight going on a quest to find a magic stone that would turn out to be me, so that together we could stop the Green Knight, who in turn would get wind of the plan and try to stop the knight who was trying to stop him -- " 

"My head hurts," you say. 

"So do ours!" scream the elves.  And in fact, their heads explode off their bodies -- like they were hit by a magic firecracker. 

"Firecracker!" you say.  "That's it!  King Richard!  Sir Irving!  Quickly!  Throw down a firecracker!" 

"Sir Green Knight," you say.  "This is a fascinating story.  Do tell us more!"
