* ''A Hero for Earth'': Wheeler accidentally activates his ring by merely saying ''fire'', and blasts the floor of the Geo Cruiser with it. A small fire starts, and Gi is forced to rush to extinguish it with her ''own'' ring.
-->'''Ma-Ti''': Wheeler! Don't say "fire" until you mean it!
* ''The Conqueror'': Zarm's yell when Captain Planet tosses his spacecraft into a volcano is just priceless.
* ''Heat Wave'': Dr. Blight's OhCrap moment when she realizes her plan failed.
-->'''[=MAL=]:''' Someone must have broken your force-field!
-->'''Dr. Blight:''' Impossible! (''looks back to see a huge wave rush towards her speedboat'') WHAT?!
* ''A Formula for Hate'': It's obviously [[{{Narm}} not supposed to be]], but the nonchalant way the doctor says, "There are only a few ways to contract the virus using drugs with needles, unprotected sex, or that blood transfusion a few years back..." without a single pause is just... ''[[CrossesTheLineTwice priceless]]''.
** And of course, "[=AIDS=] ''stinks!''"
* Wheeler in ''[[TheComplainerIsAlwaysWrong Wheeler's Ark]]'': "What's next? Endangered rocks?"
* ''Bug Off'': Captain Planet makes a mess in Skumm's lab, happily singing his own version of "I've Been Working on the Railroad".
* ''Jail House Flock'': Captain Planet is sent to jail. It's a real episode of this series, mind you.
* ''Hollywaste'': Dr. Blight kidnaps her good twin sister Bambi and prepares to steal her identity:
-->'''Dr. Blight''': Time to walk a mile in my sister's shoes.
-->'''MAL''': Her ''shoes'', maybe, but not her jeans, judging by the rate that you are eating those donuts.
-->(''GilliganCut to Dr. Blight trying to put on Bambi's jeans and ripping them'')
** In the same episode, when Dr. Blight pulls a switch on Bambi, she engages in BadBadActing. They say "We'll get KathSoucie to loop over" and Linka says "I hope they get this Soucie person." Extra funny because of who their voice is.
* ''Numbers Game'': while the pollution runs rampant and animals are all apparently extinct, the Planeteers, now in their 40s, have to call out Captain Planet, which starts out normal enough... Until he appears as somewhat obese and balding, and apparently has gotten a bit grouchy over the years.
--> '''Captain Planet''': With your powers combined-! ''(hacking cough)'' Alright, waddaya want?
* ''Frog Day Afternoon'': when the other Planeteers find a shrunken Linka's and Wheeler's empty clothes. GettingCrapPastTheRadar, much?
-->'''Ma-Ti''': Where would they have gone?
-->'''Kwame''': Without their clothes?
* ''A Good Bomb Is Hard to Find'': Hitler ([[NoCelebritiesWereHarmed with a Fu Manchu mustache]], because if they didn't, they'd get in trouble with the censors and other MoralGuardians) inflicts pain on Captain Planet in one episode by ''staring at him''.
