The early episode title was called "The Wedding."
There are several different types of wedding ceremonies visible in this episode. This includes a traditional Jewish ceremony with the song Hava Nagila and the Hora dance, and an unconventional hippie or new age ceremony in which a marrying spiritual couple wear pyramids on their heads, hold a pyramid in their hand, and are to partake in a meal of "thirteen-grain granola."
This is the first episode in which we meet Uncle Ben and Aunt Elaine. Drew describes Ben as his "little brother's wife's half-brother," and the shape of Ben's nose indicates that he is Boris's son from a previous marriage.
The title is based on Marie Antoinette's famous "Let them eat Cake" quote.
Nickelodeon originally wanted Ben to call Stu by his first name, not "Mr. Pickles," but the line remained.
Nickelodeon had qualms about the wedding cake because it was intact after going under a table, but in the final script, it remained intact.
The original script for "Let Them Eat Cake' was also to have revealed Boris & Minka's last name. In the original script, it was "Krapopkin," but it was later dropped.
Nickelodeon wanted Minka & Boris' "mother tongue" to sound genuine.
This is the fifth time where Tommy is seen wearing shoes.
This is the first time Angelica is a flower girl the next time she was the flower girl was before the start of the episode "I Do" and the third time was in Rugrats in Paris: The Movie.
