Mistletoe can be deadly if you eat it....

Catwoman: You're catnip to a girl like me. Handsome, dazed, and to die for.
Batman: Mistletoe can be deadly if you eat it.
Catwoman: But a kiss can be even deadlier if you mean it. You're the second man who killed me this week, but I've got seven lives left.
Batman: I tried to save you.
Catwoman: Seems like every woman you try to save ends up dead... or deeply resentful. Maybe you should retire. 


When I was a kid I would ask my dad to rent Batman Returns over and over... I guess liked the darkness of the characters...
