First things first thing!
(What time period are we in?)
Colonel Sandurz: Now. You're looking at now, sir. Everything that happens now, is happening now.
Dark Helmet: What happened to then?
Colonel Sandurz: We passed then.
Dark Helmet: When?
Colonel Sandurz: Just now. We're at now now.
We may tweak reality a little now and then, but in general we try to keep close to ... now. At least for now.
Now that you mention it, Now is!
