* Professor Hinkle's introduction.
* When the kids are trying to name Frosty, one kid suggests they call him Oatmeal.
--->'''Kid:''' How about Oatmeal?
--->'''Everyone else:''' OATMEAL??
* "Happy birthday!"
* Frosty attempting to count:
-->'''Frosty''': 1, 2, 3, 4, 5, 9, 6, 8...uh, w-well, I can count to 5!
* When Frosty approaches the traffic cop.
-->'''Cop''': You wanna ticket, wise guy?
-->'''Frosty''': I'd love one! To the North Pole please!
* The cop [[ISophagus swallowing the whistle.]]
** He does it again in ''Frosty's Winter Wonderland''. He first claims to be used to Frosty, but ends up shocked into swallowing his whistle after he finds out that Frosty now has a wife.
* Professor Hinkle jumping off the train and falling down the hill. Then a squirrel laughs at him when he gets covered in snow.
** For that matter, the sound effects when Hinkle is falling down the hill.
* This exchange between Frosty and Hinkle:
-->'''Hinkle''': Now, give me that hat or else!
-->'''Frosty''': Or else, what?
-->'''Hinkle''': Oh! Well, don't bother me with details!
* As flawed as ''Frosty Returns'' is, it's got Miss Carbuncle, who gives us this absolute gem of a line.
-->'''Miss Carbuncle:''' Before you know it, this darn snow turns into slush. And where's there's slush there's ice, and where's there's ice there's broken hips, and where there's broken hips there's substitute teachers!
** And later when the kids are chanting "No more snow" she provides this line
-->'''Miss Carbuncle:''' Where do you think you are, MTV?
* Frosty freaking out over the "Summer Wheeze".
-->'''Holly:''' [[DramaticallyMissingThePoint "Don't get upset!"]]
-->'''Frosty:''' "Upset?! 'Upset' is waking up and finding out someone forgot to give you a belly button! 'Upset' is discovering your nose has been stolen to play foos-ball! This ain't upset, kid! THIS IS PANIC!
