Quote: Harley Quinn and Batman

Harley: There's one thing I gotta know. Why'd you stay with me all day, risking your butt for someone who's never given you anything but trouble?

Batman: I know what it's like to try and rebuild a life. I had a bad day too. Once.

Harley: Nice guys like you shouldn't have bad days.

~ Harley Quinn and Batman, Batman: The Animated Series season 3 episode 6: Harley's Holiday

Batman: The Animated Series is another show I haven't re-watched in a long time. I do remember this episode rather well because after Harley Quinn was released from Arkham Asylum, she truly had a terrible day. From a misunderstanding about the dress she bought to being accused of kidnapping, it was a lot. And not to mention, she ended up right back in Arkham. But Batman did surprise Harley by giving her the dress she had bought earlier.
