Royal Pudding/Trivia

Trivia

 * The word shit is uncensored three times in this episode; once by Scott and twice by Mr. Mackey. The last time shit was uncensored without a special circumstance was in "It's Christmas in Canada", where the French Canadian says shit at the end of the French Canadian Song; both episodes main plots were in Canada.
 * Matt Stone, in an interview on The Daily Show With Jon Stewart, said that Comedy Central has allowed the word shit to be uncensored now.
 * Ugly Bob's ability to turn Tooth Decay into stone just by staring at it is akin to Medusa of Greek legend and her ability to turn any living thing she looks at into stone.
 * Terrance, Phillip and The Queef Sisters appeared at royal wedding but don't have speaking roles.
 * The dental hygiene play performed by the kindergarteners is a lot better produced than their last play at the end of "Helen Keller! The Musical". It's possible this is because the combined factors of the 3rd graders appeared to make their play all on their own, so it's likely the kindergarteners made that one by themselves, too and Mr. Mackey's deep feeling on the issue of tooth decay.
 * Brian Adams was invited to the Canadian Royal Wedding, despite Canada having apologized about him (the Canadian Prime Minister of Movies in "South Park: Bigger, Longer & Uncut" said that the, "Canadian goverment has apologized about Brian Adams on several occasions"), indicating Adams has caused trouble for Canada multiple times. However. his invite may have been solely to appease America.
 * Queefing and The Queef Sisters are again mentioned since " Eat, Pray, Queef ".
