One time,
Alice did something that has nothing to do with the show's scenery, and Bob replies "What is this,
Alice and Bob's Obscure TV Tropes Adventures?"
This usually happens when someone does a wrong thing, and it annoys you because it has nothing to do with anything, so you say "What is this?" and then mention a funny custom title of a show or movie. It may or may not be
Leaning on the Fourth Wall.

Western Animation
- In one episode of FETCH! with Ruff Ruffman, Ruff does this when he sees Chet pasting an underwater wallpaper on the studio wall:
Ruff: Chet, an under-the-sea motif? What is this, "FETCH! with Ruff Rumblefish"? Come on!
- Family Guy gives us this example:
Pearl: *spits* "What is this, spit soup!?"
Brian: "Tomato bisque."
Pearl: *spits* "What is this, snot soup!?"
Brian: "It's tomato bisque."
Pearl: *spits* "What is this, diarrhea soup!?"
Brian: "Look I'm not going to make you anything else, so just eat it, OK?"
