... 
Cassie: C’mon Ennis, let’s get jinky with it. 
... 
Jack: I wish I could quit you. 
Ennis: Friends don’t quit. 
... 
Jack: The only thing I like better than elk burger, is chocolate covered elk burger. 
... 
Ennis: Zoinks, I’m no queer. 
Jack: Well, duh, me neither. 
... 
Mrs Twist: John, I told you no urinating on Jack. 
Old Man Twist: It was an accident! 
Mrs Twist: You were marking your territory! 
... 
Ennis: Why's Mr Twist in a bad mood? 
Mrs Twist: He's not in a bad mood, Ennis, he's a monster! 
... 
Cassie: Let’s take his mask off and find who really killed Jack! 
(Removes the killer’s mask) 
Everyone in incredulous unison: It’s old man Aguirre!
