* Annie Potts as kooky Iona steals every scene she's in:
-->'''Duckie:''' You know what an older women does for me?
-->'''Iona:''' [[DeadpanSnarker Changes your diapers?]]
-->'''Duckie:''' Touché.

** She shoots a kid trying to shoplift with a ''staple gun'' on the face:
-->'''Kid:''' You missed my eye by an inch!
-->'''Iona:''' *smugly* Half an inch.
** "I know I’m old enough to be his mother, but when the Duck laid that kiss on me last night, I swear my thighs just went up in flames! He must practice on melons or something!"
* Duckie is a fan favorite for a reason too:
** "We don't have none of this stuff in the boy's room! Wait a minute! We don't got none of this... we don't got doors on the stalls in the boy's room, we don't have, what is this? What's this? We don't have a candy machine in the boy's room!"

-->'''Andie:''' You know you're talking like that just because I'm going out with Blane
-->'''Duckie:''' His name is BLAINE?!?! Oh! That's a major appliance, that's not a name!!!

-->'''Andie: What are you doing?
-->'''Duckie:''' I had to use the powder room, so I figured I'd come in the back.
-->'''Andie:''' I'm sure there are bathrooms all over the place!
-->'''Duckie:''' I'm not ''nine'', Andie, I know that.

** "This is a really volcanic ensemble you're wearing, it's really marvelous!"
** When bullies shove him into the girls' restroom: "We don't have none of this stuff in the boy's room! Wait a minute! We don't got none of this... we don't got doors on the stalls in the boy's room, we don't have, what is this? What's this? We don't have a candy machine in the boy's room!"
** And the infamous scene of Duckie dancing and lip syncing to Try A Little Tenderness while Andie and Iona just stare at him.
