I think it might have been Chandler that called Monica "honey" first. Because in TOW No one is ready, it goes: Ross:(about Richard's message)It's old, it's definitely old. Didn't you hear the double beep. Monica: What if it's new? I mean, we agreed not to talk again, unless we had something really important to say. Shouldn't I call him back? Chandler: Honey, you did call him back. 'Cause, it's really old. But they might have said honey before that, but that is all I can remember.
