For the speech, the team realised that they would need a lot of funny quotes in the game and also that weren't funny enough to do the work themselves, but Dan had been to see a show in Chicago by a group of performers called Second City which blew him away.  So they approached two members of the group and got them to write and perform much of the speech in the game to flesh out some of the characters and create others.  Scott Adsit was the voice of the King of Payne, Sir Psycho, the Duke or Bourbon and Merlin while Kevin Dorf voiced Howard Hurtz and the Earl of Ego.

Tina Fey (from Saturdy Night Live) also appeared as two of the princesses (the Cockney one and the plump singing one) and the cackly old maid while Andrea Farrell was the Jewish American princess and the sexy princess.  Greg Freres was the voice of the jousting announcer and one of the trolls while Francois Du Grim was Vince Pontarelli who also did the other troll.

But not all the sounds they recorded made it into the game.

Working with the Second City group was so successful, they used them again in No Good Gofers to write and perform some of the voices.
