"One Fowl Day" features Discord as a giant chicken and prompts arguably the definitive version of the old joke ever.
Barnabus: Why did the chicken cross the road?
Autolycus: To kill us all!
Hercules asks Ares alternate-universe twin to distract the original Ares. Ares 2 tries to point out that he's a "lover, not a fighter". But when put on the spot, this inspires him to use his talent by getting Ares henchwoman to fall for Ares... hard, I'd say Ares was pretty distracted.
Ares' reaction when he learns what his double has done.
"You! I owe you for this!"
"For Those Of You Just Joining Us" was full of these moments:
"You haven't heard the last of me! Wherever there's television, there'll always be B.S.!"
The scene where Hercules, posing as Kevin Sorbo, is driving along, when Ares suddenly appears in the car with him, holding a Hercules action figure:
Ares:(high-pitched voice) Oh my god, it's Kevin Sorbo! (bites the action figure's head off) Oh, oh, Momma! Momma! Oh, oh! (tosses the figure out of the car) Oh, the humanity!
Hercules eventually boots Ares out of the car.
"What is with you and animals, anyway?" "Why, what have you heard?"
Paul is nervous about the retreat:
Paul: I just got a call. They told us to pack our bags. They're shipping us out, aren't they? Why, Jerry?! Why?! Rob: Because we've all gotta learn to work together, to be creative in a crunch, to boost overall morale. By the way, Paul, your last script sucked. Paul:(dropping to his knees) I'll change my ways! I promise! I'll only drink when I'm awake! I'll tip all the show girls!
"I want action! I want romance! I wanna see Salmoneus in more episodes!"
"Love Amazon Style. As a Continuity Nod Iolaus off-handedly asks Hercules if he knows what happened to Salmoneus. Herc quickly says, "Yeah, he got arrested for tax fraud," and they go on with the episode.
