Plot
Betty's relatives from England come to America to pay a visit. Coming along are their kids -- Smedley & Hedley -- who are also fraternal twins like Phil & Lil. Unlike Phil & Lil, Smedley & Hedley dress differently, behave properly, keep clean, and finish each other's sentences without delay or incorrectness; therefore, they consider such "twinny" behavior a sign that they are "perfect twins". This eventually led to Lil wanting to be as prim and proper as Smedley & Hedley, while Phil decides to remain as messy and disorderly as usual, saying he doesn't want to be perfect.

Meanwhile, Winifred, the British twins' mother, tries to sell Betty on her method of raising twins -- a method that Betty steadfastly refuses to subscribe to.

Also, Betty gets the neighbors to pose as her relatives, as her real relatives didn't come, due to Howard's cheap invitation software that he bought at a dollar store that made the year of the date 2052.

Later, Angelica, dressed as a princess for a dance recital, tricks Smedley & Hedley into believing that she's queen of America. And as a result, they do everything she says, even bad things that they feel aren't proper.

Soon, the cake Betty presented was in the form of Buckingham Palace but Howard noticed his video camera was nearly dead so no one could eat it.

However, Queen Angelica (unaware that Betty clearly stated that no one could eat or take the cake) sent Hedley and Smedley and Lil to get the cake. Once Hedley and Smedley took the cake, they left Lil holding the bag (really meaning they left Lil to take the blame). Phil, Tommy, Chuckie and Kimi try to get Lil back out of trouble by tricking Hedley and Smedley that Queen Angelica likes a "special dance" (according to the little Kimi Finster). They lead Hedley and Smedley into dancing until they do a somersault causing the cake (they had placed in their pockets earlier) to fall. Winnie was horrified and rushes into the house to get her children clean clothes. Betty, guilty for what she had done earlier, takes Lil out and sends her back to Phil. Hedley and Smedley begin arguing as they throw mud at each other, much to Winifred's horror. Betty calms her down and takes her back to the house to give Winifred her own talk about twins. Phil and Lil reunite and start a huge row at how Phil is a nutter as the episode ends at arguing once more.

Trivia

 * Sometimes acting "twinny" can be mandatory in school if a teacher pairs his or her classmates in groups.
 * This is the nineteenth and final half an hour episode of the series after "Tommy's First Birthday", "The Santa Experience", "Passover", "Chanukah", "Mother's Day", "Vacation", "The Turkey Who Came to Dinner", "The Family Tree", "No Place Like Home", "Be My Valentine", "Discover America", "Finsterella", "A Rugrats Kwanzaa", "Preschool Daze", "Curse of the Werewuff", "Bow Wow Wedding Vows", "Murmer on the Ornery Express", and "Club Fred".
 * Of the "hometowns" Betty assigned her "relatives", is a city in New York (Boris and Minka),  is a part of  in California (Didi and Stu Pickles), Paducah is  as well as  (Drew and Charlotte Pickles), and  is the name of multiple places (but also can be used as a placeholder name for an insignificant or even fictitious town- which might have been an intentional joke) (Chas and Kira Finster).
 * This is Boris and Minka's last appearance in the original Rugrats until the reboot series.
 * After 13 minutes, there is a role reversal (in which Stu and Drew argue over who is Carl from Pacoima, because normally Phil and Lil call each other by their real names while arguing, not the adults).
 * Lil gets in trouble for something she didn't do, just as what happened to Spike in "Fluffy vs. Spike".
 * Phil's line: "A twin's gotta do, what a twin's gotta do" is similar to Tommy's original catchphrase "A baby's gotta do, what a baby's gotta do".
 * This is another episode that ends in someone's mouth. Other episodes that have that same feature are Piggy's Pizza Palace and Brothers Are Monsters.

Goofs

 * When Hedley and Smedley told Lil that she's not twins with them, their voices were switched.
