Anytime a marble enters the playing field in the same fashion as a pitch invader.
During the Fidget Spinner Collision event, a marble enters the arena and walks right into a running fidget spinner. And this was after an injury from Team Momo was caused by one of the spinners.
During the Block Pushing Event, a marble runs onto the field and tries to push one of the blocks, only to fail drastically - commentators use this to point out that this just goes to show the competing marbles are the best of the best..
It's hard not to laugh when watching the marbles in the stands do the wave.
The Theme Naming of the teams means that many marbles have silly names, with Team Momo (featuring Mo, Momo, Momomo, Momomomo, and Mimo) being a prime example.
The Hazers constantly failing at Block Pushing.

Five of the marbles in the 2018 Hubelino Funnel Race get stuck causing the race to be redone.
2019 season
The 2019 Qualifiers has the last heat of the Relay Race interrupted beacuse Limers fans were throwing trash on the course when the Raspberry Racers and Limers compete in the heat. Team Primary stops in the race claiming that the trash interfered with their performance.

Greg Woods announcing that there is a streaker on the track during the Hurdles event, followed not long after by a string of security marbles. One wonders how he manages to announce it with a straight face.
The Pinkies' Rafting heat merits a mention... not because of how they did (generally average) but because the second Greg Woods congratulates the team on a great run, the raft suddenly flips over after it crosses the finish line, gratuitously ejecting all of the Pinkies into the water.
During Round 1 of Group B of the 2019 Elimination Race, a blue marble darts across the track with Greg Woods assuming it's the Oceanics.

Then Greg Woods announces that Tide was fired right when the starting gun goes off.

The Jungle Jumpers finally lived up to their name in the Qualifiers, by jumping out of the Funnel Endurance track.
They then followed it up by winning the gold in the subsequent Sand Mogul Race, which fans noted is the exact opposite of a water event.
And then they went and beat the O'Rangers at the Aquathlon! Granted, the Oceanics didn't get on the podium, but there is a certain hilarious irony to this kind of Crack Defeat. Greg Woods got so distracted by the team suddenly doing well in a water event that he almost missed commentating on the following heat.
After the High Jump the O'Rangers had a 35 point lead in the standings and if they kept this up they would guarantee victory. The following two games then showed abysmal showings from the team, with them losing the Aquathlon to the Oceanics and coming dead last in the Collision event.
Incidentally, despite these two performances that can be considered downright embarrassing considering who they are, they are only behind the now first place Savage Speeders by 5 points with one event to go... which is where they stayed after the Marathon, unable to get any of the medals. Which means that, indirectly, the Oceanics cost the O'Rangers the entire league.
During the collision event, the Thunderbolts show off their comfort with the event by having a single marble, each time a different one, spin in the dead center of the arena in the quarter-, semi-, and finals - treating it more like figure skating than the Rugby-inspired tackle it usually is - and despite it, they manage to land their first medal in the event.

PA Announcer: Attention. Greg Woods, please make your way out to the commentary booth, as the race is about to start.
2021 season
Just about every Sand event has at least one instance of an insect interfering with the track and causing it to be delayed.
The Sand Rally in the Friendly Round gets delayed for a bit because an insect was interfering with the track.
And in the Sand Mogul Event, another insect interferes with the starting gate for the final race.
The start of the Sand Rally's first heat had to be slightly delayed because of yet another insect, and Greg makes sure to state that they want the event to be safe for marbles and insects alike. The eight marbles of the second heat all run over an ant within the first couple of seconds.
During the Qualifiers in the Wave event, the Green Ducks do a little dance after their performance.

Cue Green Eye stealing the record from Choc only for Greg to respond, "And why not? Another Marble League Record!"

In the "Rafting" Marble League event, five runs in a row between three teams get wedged early in the race, seeing the Balls of Chaos and Midnight Wisps fail to finish! Greg Woods can barely believe it as he commentates!
Also in "Rafting", the Pinkies pull a stick from behind during their run which is believed to have slowed them down only for them to finish second.
Team Galactic finally overcoming the Team Galacfifth meme in the penultimate event by guaranteeing them fourth or higher in the overall standings, then finishing fifth in the final event.
A post-season crossover video with Hevesh5 (who does domino rally videos) featured a short eight-team race. It was won by the Oceanics - a team that had failed to qualify again and subsequently bombed out of the year's Showdown, proving that the only times they do well are all the times that don't actually matter.
