Rational poster: <List of points as to why flamer is a tool>. That is all.

Flamer: <Weak attempt at continuing to argue, change the topic, bait and switch, etc.>

Flamer: Wait, I'm not done with you yet!

Flamer: Your silence just shows you know I'm right!

etc, etc, ad infinitum/nauseam

Also, it was the closing line in M*A*S*H years before it was uttered by Darth Vader: P.A. Announcer: (clears his throat) Attention. Tonight's movie has been "M*A*S*H." Follow the zany antics of our combat surgeons as they cut and stitch their way along the front lines, operating as bombs and bullets burst around them; snatching laughs and love between amputaions and penicillin.
Colonel Blake: (Watches as a jeep rolls away) Did Hawkeye steal that jeep?
Radar: No, sir. That's the one he came in.
Colonel Blake: Oh, very good. Come along, my dear.
(He and Lt. Leslie leave)
P.A. Announcer: Follow Hawkeye, Trapper, Duke, Dago Red, Painless, Radar, Hot Lips, Dish and Staff Seargeant Vollmer as they put our boys back together again.
SSgt. Gorman: Goddamn army.
P.A. Announcer: That is all.
(a gong sounds and the screen suddenly goes black. End of movie)

"That is all"

Adam's post in LiveJournal:
"I just tilted my head back and squeezed a good sized squeezeful of ketchup into my mouth.

That is all."

Thanks for the blow-job bitch....that is all.

That is all.
