Quote from : Batman: Mask of the Phantasm Movie

The Joker: [when Batman picks up the phone in Andrea's apartment] Hello, anybody home? Listen, boopsie, even though you never call and never write, I still got a soft spot for you. So I'm sending you a fun gift, airmail! And there's no use jumping out the window this time, toots...
[Batman looks out the window and sees a toy Joker plane flying in carrying a bomb]
The Joker: The plane of the future is going to make you history!
[Batman throws a Batarang, exploding the bomb outside the window; the blast knocks him back against the wall, and the phone is left dangling]
The Joker: [laughing] Hello? Hello, operator? I believe my party's been... disconnected! HA-HA-HA-HA-HAAAAA!
