Louise's idea of cutting off someone's ear to go all the way as an artist is a reference to Dutch painter Vincent Van Gogh who cut off his own left ear in a rage.
This episode inspired the ComicXposure exclusive variant cover for Issue 2 of the Bob's Burgers Comics. Which features the kids opening a gallery of Gayle's anus paintings.
In then flashback to Gayle on the mountaintop, a song that parodies Celine Dion's "My Heart Will Go On" plays.
Devin McJimsey who is roped in by Louise to work on touristy-crap art is named after Bob's Burgers office coordinator Devin McJimsey. He is renamed Michael Carlish later in the series and has a different voice and wears different clothes.

Linda's "butts" dream is a parody of the famous Pink Elephants On Parade segment from the 1941 Disney movie Dumbo.
When Linda comes back from lunch with Gayle she is wearing her apron, but in all other shots after this apart from when Bob says "Look, Gayle, I'm gonna level with you", she isn't wearing it.
After Gayle says "Oh my God", the burger of the day board changes from the Salvador Cauliflower Burger to what appears to be a chalk animal anus drawing.
When Louise gives Bob the rhino anus painting to hang up, it reverses when rotated unlike all the other paintings.
When Bob goes to confront Edith about the paintings at around 14:21 you can see a booth on the right side that appears to have been shrunk and when Bob turns around to walk out the door he steps on the booth.
When Bob is getting arrested the mics on the officers' shoulders switch from left to right then back again throughout the scene.
