Courage the Cowardly Dog is known by many to be a horror-comedy series. Just like some episodes tend to avoid the comedy part of its horror-comedy status, resulting in Nightmare Fuel, these episodes tend to avoid the horror angle of its horror-comedy status, resulting in hilarious moments. Here are some examples:
Pretty much all of "Cajun Granny Stew", since the whole thing plays like a Looney Tunes episode, but one part in particular is hilarious. The Cajun Fox has kidnapped Muriel and is getting away in a steamroller, so Courage tries to stop him with the old fake detour trick: he switches around a Road Closed sign so that the Fox will drive into a bunch of rocks instead of going the right way. The fox doesn't buy it, runs over the sign and Courage, and then immediately falls off a cliff.
"I'm rollin' this Granny in flour...makin' the dish of the hour..."
The plane scene, where the fox displays a Courage-worthy toothy scream-twice in the space of about 30 seconds.
Eustace reciting an exorcizing spell: "Hullabaloo, and howdy doo! Musty prawns, and Timbucktu! Yeltsy-by, and hibbety-hoo! Kick 'em in the dishpan! Hoo hoo hoo!!"
"The Gods Must Be Goosey". Second only to "Cajun Granny Stew" as the funniest episode of the show.
HONK HONK.
How in god's name has Little Muriel not been mentioned? Basically everything after Muriel gets de-aged qualifies as one solid moment of funny. The Macaroni scene in particular is epic comedy.
During the scene where Courage and Muriel are on a plane, Muriel runs up and down the aisle, arms spread apart, complete with airplane noises. Two people jump out of the plane, including the pilot, because they can't put up with her, anymore. Cut to Courage's completely deadpan expression, that can only be summed up into, "The shit I have to put up with..."
Crazy plunger lint lady: They're doin' terrrrrible thiiiiings over theeeere. (pause) But-cha ain't gettin' MY lint!
The episode about the Sand Whale contains some rather hilarious moments. For example-
Eustace: (Sliding around inside his chair in the whale's mouth) Look, I found me chair!
Muriel: (Deadpan) Well, at least you're comfy.
And later-
Eustace: (Now inside a fridge inside the whale's mouth) I found the fridge!
"I'm glad everything worked out ok." "But the whale's got me Ma." "(Smiles) I'm glad everything worked out ok."
The episode where the computer gets a virus and Courage has to go inside is pure hilarity. Especially when Muriel accidentally clicks on an adult website. Courage's reaction is priceless.
"2+5=BOB!"
Just about anything the computer snarks is simpy hilarious:
Computer: If Johnny has three apples and Davie has two apples, why don't they just shut up and eat?
King Ramses's second curse: A really annoying song. KING RAMSES! The man in gauze, the man in gauze! Considering that the first curse is flooding and the third is locusts, this is kind of Arson, Jaywalking, and Murder.
From the same episode: "Judgin' by the markings and the obvious age of the relic, I'd have to say it's..... GARBAGE!!!
"From King Garbage! Of the Garbage Dynasty!"
When the first curse is foiled, he goes, "Aw, come on!"
In the flashback episode, Courage was looking for his parents, and when he opened a door, a woman was taking a shower and screamed. Courage promptly shuts the door, but a few seconds later, he opens it again.
The entire episode of "Courage Meets The Mummy".
The bigfoot episode. Courage is worrying over the danger Muriel is in, and even has a fantasy bubble of bigfoot punting Muriel like a football, across the entire length of the field, and through the goal posts.
And the epic chase scene when the Deer started hunting Eustace and Courage, complete with In the Hall Of the Mountain King in the background and the chase ends with Eustace getting mauled by a Siberian Tiger.
From Magic Tree of Nowhere:
*Eustace and monster fish come out of moat together*
Eustace and Fish singing in unison: For ye will bend and tell me that you love me!
Fish: BBBAAAHH! *eats Eustace*
The "Rockem Sockem Robots"-style fight from The Duck Brothers.
*cut to Courage frantically pressing buttons on the remote*
*cut back to Muriel, who is now walking on the ceiling*
At the end of "Family Business" where Courage and Muriel try to convince Basil to give up his life of crime. As he looks to Eustace for his input Eustace is seen being attacked by a giant squirrel which was never mentioned or seen before then. The scene literally just cuts to him being attacked while the others were talking. This is made even funnier by the fact that everyone just ignores the attack and continues talking.
Family Business as a whole was one of the funnier episodes of Courage. Basil's switches from 'hardcore criminal' to 'loving family member' are so bizarre that even Muriel admits he's insane.
This pretty much sums up the episode:
Basil: "Nigel, why are you tyin' up Mama Mashed Potata's and Uncle Twinkle-toes?"
(Courage, Muriel and Eustace stare blankly).
The whack-a-mole scene from Night of the Weremole. And the Mood Whiplash it caused only added to the humor.
And to think Eustace can't get any points in that scene because Weremole Muriel keeps on dodging his blows. I like to say that's not fair!
In the shadow episode, Eustace has been convinced that Courage is making fun of him by the Living Shadow. He chases Courage to the kitchen and starts throttling him, shouting "Say 'uncle'!". Then Muriel dashes in in full Mama Bear mode, One-Woman Wail in the background, as she nails Eustace with her rolling pin (off-camera). As she leaves the kitchen, Courage (who she's holding in her arms), quietly remarks "...Uncle?"
This quote from Klub Katz, showing Eustace's 'love' towards his chair, had me in stitches...
(As he's flung from the cruise ship and across the ocean) Eustace: No sir. Not gettin' outta' this chair.
While The House of Discontent was very scary, it did had some funny moments like Eustace's reaction when the family first meets the spirit of the harvest moon.
*Eustace: Would you look at that.
*Muriel: It's a floating head!
*Eustace: I was talking about that leaking pipe.
The episode with the cursed library book. While the Transformation Sequence for Eustace and Muriel was pretty freaky, Courage's reaction was utterly hilarious. It's difficult to describe, but I'm going to say that instead of his usual scream of terror, Courage can only respond with some weird visual gags that can only be described as a visual version of a Flat "What.".
