A jovial shoutout to insider-joke stupidity, disguised as a greeting—for when you care enough to send the veritable jest.
Jerry joked with George that, when Clare, the woman Jerry was then dating, fell asleep, her stomach stayed awake and talked to Jerry–the voice overblown and jolly, like a caricature of a human being: “Hel-looooo!” followed by “Talk to meeee!” or “La-la-laaa.” Jerry and George laughed it up with Kramer, who also picked it up (Elaine just put it down)…until Clare found out about it and, disgusted, basically told Jerry It’s me or the voice. And, just like that, Jerry’s hel-lo became a good-bye.
This is the voice of one talking behind another’s back. That someone you are talking about walks into the room right as you and a friend are talking about that someone, and up goes your voice, silly big, the “o’s” booming out of one side of your mouth, Hel-looooo! The gusto of the faux greeting will leave the butt of your joke thinking that nothing but kind things are going on here.
Don’t let one too many know what’s going on here. The fewer who are “in” on your joke, the better, as Elaine pointed out when, hearing “the voice” for the first time, she asked Jerry what it was:
Jerry: “Oh, it’s just this stupid thing.”
Elaine: “Well, I’m sure it’s stupid….”
That is to say, at some point the stupidity of your joke will be revealed. And it is at this point that, as George, Kramer, and Clare illustrated, your friends will likely abandon you. Unless, of course, that sort of thing doesn’t bother you—in which case, by all means, continue the voice, starting with those “friends”:
“Fare thee welllll! La-la-laaa.”
