The episode confirms SpongeBob's birthday to be the 14th of July, 1986 (which would have made him fifteen at the time), something that previously came up in a dream in 'Sleepy Time'.
This marks the first physical appearance of the French narrator when Spongebob runs him over. The second appearance of the French narrator is in 'Feral Friends', when Sandy contacts him on his submarine and he teaches her about Neptune's Moon.
When Mrs Puff arrives home and the lights are turned on, if you look at a painting on the wall, you will see an infinity loop.
