Supercuts meme: Obsessive montages
Rex picks up what Waxy puts down: Supercuts, videos that cull discrete but recurring actions/words from TV episodes or film -- e.g., Shia LaBeouf saying "no no no" in Transformers, the Lost characters saying "what" -- and string them into a sequence, thus bringing their frequent use into relief.
No matter the topic (people being shot, somebody saying "f*ck", etc), the result's always funny. It's an old comic staple that repeating a thing three of four times isn't funny, but repeating that thing seven or eight times is (this might also be connected to our aesthetic appreciation of a simple thing repeated visually multiple times, and thus creating a complex whole). The repetition creates a constant that is then varied in context or tone by the speaker. Hence the Bud Light dude commercials, and in a more complicated sense, The Aristocrats. Quoting old Northrop Frye, "Repetition of action leads to tragedy. Repetition overdone or not going anywhere belongs to comedy."
