When this episode first aired, the scene of Bart using book pages for the sacred wedding fire originally had Bart tearing out pages from The Bible. Mike Scully (and a few viewers) found that to be offensive, so all reruns (including the DVD version) replaced it with a scene where Bart is ripping pages from a hymn book for the fire. Ironically, the censors allowed Homer to burn a Bible in "Dial 'D' for Diddly," though the main difference is that the Bible wasn't a real one (it was a radio Homer was using to force Flanders to kill his enemies).
The Foreigner song "Hot Blooded" plays over Apu's bachelor binge, and he dances in a manner similar to Riverdance.
In the wedding procession, Apu is seen on a howdah, a covered pavilion on the back of an elephant or camel.
The scene where Moe walks on and off the stage without breaking his stride was loosely based on a moment that occurred during a stand up show of comedian Red Foxx. During a show in Las Vegas, Foxx came on stage to the Sanford and Son theme song, only to find that there were very few people in the audience. Foxx reacted furiously refusing to do a show with such a small audience and walked off. The house orchestra, puzzled by Foxx's leave simply played him off with the Sanford and Son theme song again.
That Sanford and Son theme song was played in Trash of the TItans during a walk by former trash comptroller Ray Patterson.
The events of Apu's wedding were later referenced in the beginning of It's a Mad, Mad, Mad, Mad Marge, where Bart when convincing Marge to host Otto and Becky's wedding at their house points out that they still have the decorations left over from Apu's wedding, including the groom's elephant, which Marge makes Homer get rid of as a condition to allowing the wedding to occur.
In The Sweetest Apu, Marge watches footage from the wedding, where Manjula and Apu are dancing and Homer gives a jazz song to the musicians. It is unknown if the footage we watch in that episode takes place during or after what we see in this episode (with Apu and Manjula dancing and Homer being swung around by the elephant).
