- The Riddler: Riddle me this, you two. What is cold, but still burns? What will eat you if you drink it? What...
- Harley Quinn: Acid.
- Batman: It's acid.
- The Riddler: I am not done! What is... wait... did I say the thing about cold but still burns?
- Batman: Yes.
- Harley Quinn: Right.
- The Riddler: No!
- Harley Quinn: Because it's acid.
- The Riddler: Okay, it's acid. I'm dropping you in a pool of acid.
- Poison Ivy: You helped me. I can be around people now. You know, I mean, I hate it, but I can do it without vomiting.
- The Joker: It just seems like every time I turn around, someone's gushing over the Riddler. I mean, seriously, his whole schtick is being the world's most indirect asshole!
