- Here We Go Again!: At the end, after dealing with the titular social network and service, Thrasher and Blastus then try out a dating website. Cut to two days later... and it's implied that they go through the same events again on there.
- If I Can't Have You…: At the end, when it becomes clear that Thrasher and Blastus no longer want anything to do with it, Frenemy decides that, if it can't have them as friends, then it will kill them so that nobody else can.
- Killing Your Alternate Self: After going back in time, the older versions of Blastus and Thrasher deal with the issue of having doubles of themselves by feeding their younger selves to a trash compactor.
- Phlebotinum Overload: Frenemy is defeated when everyone on the planet sends it thousands of notifications, causing it overload and explode.
- Special Guest: Jack McBrayer as Frenemy.
- Take That!: The episode is a merciless parody of Facebook, Twitter, and social networking sites in general.
