In our daily badinage on orchestral tours of the US of A in the Good Old Days, we got into the habit of handing over to each other by imitating CNN’s signalling style:
And they say there could be more revelations to come. Wolf.
[Wolf Blitzer,  of course, was an “anchor”. Considering that Britannia Rule the Waves (just dig that funky optative verb there, folks—”You Wish”, as the Argot of Yoof  would have it), it’s curious how we don’t much go in for anchors.  I guess we consider them beneath us…]
Rather like my teacher Paul’s empirical use of classifiers, we interpreted it as a fixed signoff at the end of every sentence, which led us to:
I thought the Adagio was really too slow last night. Wolf.
I’m starving. Let’s go eat.  Wolf.
Usually, rather than an interrogative (“Wolf?”), it’s declaimed confidently in the matter-of-fact descending fourth tone.
It does seem wise to keep such signals simple:
On stage at the end of a concert, among ourselves we would also adopt the brilliant casual signoff,
Well folks, I guess that’s just about it for tonight!
This works particularly well after an obscure or meditative work. Like:
Join us next time for another whacky episode of Ockeghem’s Marian Antiphons!
 OK, we Brits have our own proud tradition of silly names, but American names are in a class of their own. Following the credits at the end of a Hollywood movie is like reading an avant-garde poem, plunging into an exotic cornucopia containing all the cultures of the world. Though if Tweety has anything to do with it, there will be no more films, no more culture, no more world. Nothing, as Stewart Lee observes.
 Unless you count Piers Morgan, who tries unsuccessfully to lose the initial W.
 For me at least, there’s an illicit thrill in uttering the formulation “go eat”. Similarly for “Can I get” instead of “May I have”—a quick web search reveals mainly the usual pompous British indignation yearning for ethnic purity, though one writer suggests rather elusively that “Shakespeare probably would have loved it” (as in the little-known line from Romeo and Juliet: “Can I get a Diavola and a supersize Coke to go?”). Can I get or May I have, that is the question. See also my thoughts on “Who is this?”.
