Seeing that Batcow was apparently chewing his breakfast bagel (and not grass, as he’d originally thought)…

Tim [to Damian]: Dishonor! Make a note of this: dishonor! Dishonor on you, dishonor on your cow!

When asked to describe him and his brothers…

Dick: … in the simplest terms and the most convenient definitions… But what we found out is that each one of us is a brain, and an acrobat, and an heir, and a criminal.

Jason: *tries to stifle a laugh*

Tim: What is your problem? Does seeing me fail somehow make you feel better about your sad, miserable life?

Jason: *wipes tears off eyes*

Jason: It does, 100%.
