The voices are still coming from the pipe: 

"You know," King Richard says.  "My mother made pudding like this.  Or rather, my mother's servants did." 

"I like servants," Sir Irving says.  "But not eating-wise.  I like pudding for that.  But servants are likable in a serving-wise sort of way." 

"Help us!" you shout into the pipe.  "King Richard!  Sir Irving!  Help us!" 

"I was wondering if maybe I could get in a word edgewise," the Green Knight says.  "You know, before I slay you all." 

Just then there's a flash of light.  Out of the clouds appears a tall, coughing figure in robes with stars and moons. 

"Hello," says Goofdaln.  "Had some trouble remembering that teleportation spell, but better late than never, I always say.  I'm here to rescue -- " 

The lion eats him. 

"Thank you," says Turing the Tester. 

"Thank you," says the Green Knight. 

"Thank you," you say. 

The Green Knight claps his hands once.  "Now, is there even just a little time for exposition?" 

"Yes," you say.  "It'll give me time to plot some way to stop you from your evil plans -- plus allow me to find out what those plans are." 

"No," you say.  "Although I must admit that my argument in the first link is quite persuasive."
