- The 2012 Berlin show "Best of Musicals" included a Disney medley with "Poor Unfortunate Souls" (from The Little Mermaid). Whilst Ariel was singing as Ursula stole her voice, the actor for Ursula shouted "Sing, my Angel of Music!" This is not in the original; it's a reference to the title song from The Phantom of the Opera, where Christine sings similarly high note sequences upon the Phantom's urging.
- In the Mach20 fan translation of Assassination Classroom, Kayano says that falling in love was like being "shot through the heart". (She then explains- less overtly- that Nagisa's to blame.)
- Neopets often has shout-outs in their item descriptions. For example, the description of a Sand Sled is "Snow? Where we're going we don't need snow."
- SCP Foundation, SCP-261 ("Pan-Dimensional Vending"). One of the items SCP-261 dispensed was a white cake in a box labeled "TASTE ME". When eaten it increased the subject's size by 7 inches and their mass by 13.6%. This is a reference to Alice's Adventures in Wonderland, in which Alice ate a cake with "Eat Me" written on it and grew to tremendous size.
