* Several of instances involving Jeremy, like a running gag involving him trying to make a love nest out of yarn.
** Not to mention his ''disastrous'' attempts to [[BadlyBatteredBabysitter babysit]]. Poor guy...
** He temporarily lightens up the otherwise tense scene with Dragon by accidentally sneezing right into the cat's face.
** Just the fact that Jeremy, a bird, is ''allergic'' to cats.
* Martin and Auntie Shrew exchanging insults. Funny because Martin is just a child.
* Brisby herself has funny moments. Pretty much saying no to Timmy wanting to go outside when he's whining about being in bed sick.
* Mrs. Brisby ''flirting'' with Jeremy to convince him to watch her children!
* Most of Brisby's scenes with Jeremy, just for how clearly he's getting on her nerves.
** Jeremy bringing up the topic of him wanting to meet females, leading to this exchange.
--->'''Jeremy''': None of the girls I meet want to get serious.\\
'''Brisby''': [[DeadpanSnarker I doubt they'd survive]].
** When he asks for her advice in meeting female birds, she tells him to be "athletic."
* Jeremy taking Brisby on his back to see the Great Owl. She's already extremely nervous of seeing the owl (for obvious reasons), but she can barley hold onto Jeremy due to his reckless flying.
-->'''Jeremy''': Nice evening, huh? I told you you'd love flying.\\
'''Brisby''': I don't know how I let you talk me into this!\\
'''Jeremy''': Aw, don't thank me, Mrs. Briz. When we get to the Great Owl, he'll know just what to do about everything!\\
'''Brisby''': Owls eat mice!\\
'''Jeremy''': Ummmm...only after dark.
* A bit of BlackComedy would be Mrs. Brisby's nervous laughter as she tries in vain to politely talk to Brutus as he's ''attempting to kill her''!
* Justin’s introduction goes from tense to amusing in a matter of seconds:
-->'''Justin:''' (''whispering playfully, while grabbing Mr. Ages from behind'') Reveal thy name!\\
'''Mr. Ages:''' Justin! You featherhead! Get your hands off me!
* As they arrive at the door to the meeting hall, Mr. Ages decides to listen through the door at the ensuing discussion. Justin, however, just picks Ages up and carries the old mouse commenting, "Come on, you suspicious old goat."
* The small moment of SnarkToSnarkCombat between Justin and Jenner when the former walks into the meeting hall with Mrs. Brisby and Mr. Ages.
-->'''Jenner:''' Hear me! The Thorn Valley Plan is the aspiration of idiots and dreamers. We--[''notices the trio and starts chuckling''] ...[[StealthInsult We were just talking about you]].\\
'''Justin:''' That's refreshing, Jenner. Usually you're screaming about us.
-->''(The court laughs, with [[ActuallyPrettyFunny even Jenner amused at the retort.]])''
* A rather small one, but the moment that started the shipping between Mrs. Brisby and Justin has a pretty good exchange of dialogue.
-->'''Mrs. Brisby''' ''(looking deep into Justin's eyes like she's smitten)'': How beautiful...
-->'''Justin''' ''(in a "well now" sort of voice)'': Ma'am?
-->'''Mrs. Brisby''': Oh, uh... ''(Embarrassed, she laughs.)'' [[VerbalBackspace The lights, they're quite lovely.]]
* The exchange between one of the home owners and a NIMH agent becomes this given how, while NIMH wants to destroy the rose bush to cover up their involvement in creating the rats, the home owner in question is elated he's getting a free exterminator service.
* While the scene at the end where Jeremy [[CrashIntoHello meets]] [[MeetCute the girl of his dreams]] is equal parts funny and heartwarming, we then get this comment from Cynthia.
-->'''Cynthia:''' Look, Mommy! Another turkey!
