* The episode, "Incident at Chlorine Lake", where Bill the Lab Guy is in an observation cage, watching the Trophy Bass. Then it starts ramming the cage, super dramatic music plays, and Bill yells, "Oh no! I was afraid of this!" The combination of absurd imagery, the music, and Bill's [[DullSurprise tone of voice]] makes it a really funny scene.
* "Yay! The mayor's toast! Boooo! So are we!"
* Bill un-brainwashing the citizens by calling in his personal friend, ''Lou Rawls'', to unhypnotize them by singing his own subliminal song.
* After the Mayor unveils the big baby at a circus sideshow:
-->'''Thunder Girl:''' What a cute baby.\\
'''Stinky Diver:''' What a grotesque parody of human life!
* Any time the Chief says "BLAST IT!"
* The Body-Eating Virus episode has the Flesh infected with the dread disease. Bill shows the heroes video feed of what's happening to him... and we see a game of VideoGame/PacMan.
** From the same episode, the League have been infected, and are all reduced to just heads.
-->'''Announcer:''' Meanwhile, the League has gathered together for a touching, final farewell...
-->'''Chief:''' Blast it! If I had any legs left, I'd stomp all you fool-heads into the ground!
* When the League is on trial for their incompetence, and the Flesh is the only one who has yet to make a defense statement.
-->'''Chief:''' (Looks to the camera) Well, we'll see you at the reunion show!
* The Chief's reaction to the League being cloned in 'Tears of a Clone''
-->'''Chief:''' AAAHHHH!!! HOLY MOTHER OF MOTHERS!!
-->'''Leagues:''' Hi, Chief!
-->'''Bill the Lab Guy:''' Oh no, I was afraid of this.
-->'''Chief:''' No, you weren't, you pointy-headed geek! ''I WAS!!''
