Samurai Jack/Funny

• In "Chicken Jack", the only reason that the spell cast on Jack wears off is because the moody wizard flew off the handle upon the cock fighter manager bumping into and accusing said wizard of not watching where he was going. The spell reversed Jack's condition, but turned the manager into a chicken himself. The confused look on said wizard really sells the whole bit.
• When he discover's Jack's blade is an Empathic Weapon, Aku's flaming eyebrows go out.
• There's one moment in "Jack and the Hunters" that always gets this troper: Jack, cornered by the Emikandi, runs into a nearby ambiguously tall building, and discovers an orange button with an arrow pointing upwards. Figuring out what it's used for, Jack presses the button, and the room he's in starts to move up (turns out it's an elevator). This forces the Emikandi to follow him into the next available elevator and pursue him in a hilariously long, silent chase sequence where Jack continuously foils the Emikandi by getting off his elevator and simply walking into another.
• The entire of the episode "Aku's Fairy Tales", which focused on Aku's brand of storytelling to a group of young children:

Aku: Once upon a time... there was a little girl with an adorable red cape and GREAT FLAMING EYEBROWS!

Aku: The spear struck the beast, transforming him into....BEEF JERKY!

• "That rock didn't move by itself, Aku!" "Yes it did!"
• From episode 21, the one with the flatulent dragon, the Scissorsmith offers Jack the following advice:

Scissorsmith: At the fork in the road, follow the rocky path! It will take you to the Dragon's Lair!
Jack: Where will the other one take me?
Scissorsmith: Space Ace!
(Cut to Jack's baffled face as a goofy sound effect plays)

• Jack's goofy smile right before he realizes he's been had in the first act of "Jack's Tales".
• "Jack is Naked", especially when he has to dress as a princess.
• The entirety of "Jack's Sandals".
• Most of Jack's interactions with the Scotsman. Most notably when they're challenging each other at contests to see who gets to row the other back home from a remote island. It all comes down to an epic battle of thumb wrestling.
• During their first meeting, the Scotsman's extremely long insult.
  • Coupled with Jack's complete failure to retort or indeed react in any way whatsoever.
  • A few moments later, they both fall from a bridge into the river and watch their broken possessions floating away:

Scotsman: (seeing Jack's hat) AHAHAHAHA!
Jack: (smirks as the Scotsman's deflated bagpipes float past)
Scotsman: ...SHUT I'!

• • In the episode where the Scotsman goes on a boat and discovers that Jack has lost his memory, Jack talks like a Totally Radical surfer dude.
• Aku's epic Lampshade Hanging during "Aku VS Jack".

Aku: Oh, put that thing away. We all know what's going to happen. You'll swing your sword at me, I'll fly away, and probably say something like, "I'll be back, samurai!" And then I'll flutter away over the horizon, and we won't see each other for about a week. And then, we'll do the same thing all over again.

• • Jack, disbelieving what Aku just said, then proceeds to swing his sword at him, Aku turning into a bat form, fleeing, yelling, "I'll be back, samurai! You'll see! HAHAHAHA!" He flutters away for long enough that Jack starts getting thoughtful before turning back and saying "See what I mean?"
    • And guess what happens at the end of the episode.
• Pause at the very beginning of the portal sequence in the intro. Look closely at Jack's face. Try and hold in your laughs.
• The first episode of season 2, "Jack Learns to Jump Good", opens with Jack having just fought his way through a horde of Aku's drones to reach a time portal, when Aku suddenly appears and snatches the portal away. Aku then proceeds to dangle the time portal just beyond the reach of Jack's jump and giddily watches Jack hopping up and down trying to reach it.
• The Good, the Bad, and the Beautiful (XXIX):
