Batman: You know who I am. You know what I can do. But I am holding a small child here. And if you make me do anything that could possibly endanger this baby... You will be very, very sorry. *pause* Forever.
And the thugs immediately surrender their weapons. The moment is broken, though, when they have to tell him he's holding the baby wrong!
The Joker and Harley get one in Batman Adventures #3. After a story arc in which shock therapy by Arkham turns Mr. J into a pacifist, Harley finds herself less attracted to him. During a climactic confrontation with Batman, she gets fed up with her puddin's groveling. In an attempt to snap him back to his old self with jealousy, she tells him that she wants to be with Batman now and even kisses him (much to the Dark Knight's shock). Joker responds by beating the living hell out of him. Batman does overpower him and win in the end, but seeing anybody manage to catch the Goddamned Batman off guard is quite impressive. All for the love of his Harley.
Commissioner Gordon: Be quiet, Joker. Nobody believes you - You're a raving lunatic. Joker: A homicidal lunatic, thank you very much. Harley: Didja hear that, everybody? My boyfriend's back!
