* RealLifeRelative: The actor who plays Allison's brother Marcus is Dondre Whitfield, husband of Salli Richardson-Whitfield. Makes this bit of dialogue sort of meta-Heartwarming.
-->'''Allison''': Jack Carter might not have the highest IQ in town, but he's the smartest man I know.
-->'''Marcus''': He married you, didn't he?
* Deputy Andy is one big ''ToyStory'' ShoutOut. One of Woody's pullstring phrases is "You're my favorite deputy!", something his ''owner'' Andy would have heard quite often, no doubt. And Eureka's Andy is a highly advanced android, something Woody's ''other'' favorite deputy, Buzz, would be quite familiar with.
