The final scene of "cH - Fixer": Matt discovers his Primes are gone, drops his brand new Xbox, and gets kicked in the balls by Graham. The joke is the culmination of about 15 minutes of setup and almost every subplot in the series up to that point.
- The "Mailbag" video indicates that this scene is Paul's favorite punchline in the history of the site.
The first season finale; just when it looks like Geoff's won and is about to delete everything related to LoadingReadyRun, the ball-kicking robot Paul invented several episodes ago before basically being completely forgotten rides in, Ride of the Valkyries playing, and kicks Geoff in the balls, leaving him immobile so Graham can steal the iPhone he was about to delete everything with away.
In the season two episode "The Arms Race", Matt and James treating their Nerf war as Serious Business was mainly funny. Then Paul, misinterpreting a request from Graham, appears with a handmade weapon that is essentially a Nerf BFG.
Paul: I call it...Dartageddon.
Jer constantly clubbing Alex in "Bros Clubbing Bros", only getting clubbed once. Then Alex gets dangerous. Doubles as a Call-Back to their recent Desert Bus for Hope marathon, where a similar thing happened.
Alex's amazing magic tricks in "It's Magic".
- Also the crew finally beating him:
Graham: What we're going to do is pat you down...(pats Alex down, revealing several hidden cards)...and we're going to watch you very closely, while you face...Kathleen.

Paul is a walking Moment of Awesome factory throughout this spin-off. He decides to start playing Magic: The Gathering, but he applies his general "professor" attitude to it in order to get the best results. In other words, he goes insane with research, testing, and searching, creating the best decks possible. Just watch the second episode to see how far he goes. And it works.
- And, during a tournament, Paul places third place, despite it being his first tournament and first time playing against anyone other than other crew members.
- Most recently, he finishes top-8 in a Grand Prix, which qualifies him for Pro Tour Magic Origins. Quite the accomplishment for a guy who started playing just three years prior!
