In this, the last episode written by GoldenAge ''Simpsons'' writer, John Swartzwelder, The Simpsons are going to England after Bart raises money from his treehouse museum, where Homer personally meets The Queen...by running her down with his car.
* TheBeautifulGame: Homer justified an act of violence on a yellow card a referee gave. By his own admission, the only word he understood was "gave" and he's not even sure if [[SeparatedByACommonLanguage its meaning in England is the same as its meaning in America]].
* DistaffCounterpart: [[spoiler: Homer has one -- a half-sister who looks like the Homer-esque woman who drove by Bart, singing "I Am Woman, Hear Me Roar" on the season four episode "Brother From The Same Planet".]]
* AFoolForAClient: Homer represented himself instead of hiring a barrister. Marge allowed it because she didn't think Homer's chances were good enough to be damaged by the decision. Not surprisingly, Homer managed to offend the judge, jury and British public at large even further (he was on trial for crashing into the Queen's carriage)-ending up in the Tower of London.
* MarySue: Invoked in-universe when Lisa meets J. K. Rowling and asks her how Harry Potter will end. J. K. sighs and says "he grows up and marries you." [[DeadpanSnarker After all, it's what Lisa wanted to hear, right?]]
* TheScottishTrope: And it's also bad luck to wish a thespian good luck [[ExactWords using those exact words]] too.
