On days when they're particularly mad at Batman, the Batbrats have been known to say how disappointed Alfred must be to watch the boy he raised run around as an emo bat furry in spandex. (You somewhat frequently are dating a lady who dresses up as a cat, you're a furry!)
Bruce: Dating a woman dressed as a cat does not make me a furry.
Jason: Dating said cat while dressed like a bat makes you exactly that.
Stephanie: Hey nice rhyme.
