Which reminds me of the following:

Sorry for the little offtopic and the german:

The clip is dubbed with the german dialect "Kölsch" which is spoken by people around the city of Cologne.

Here's a quick translation:

Emperor: Now I've forgotten what I wanted to say. Just a moment ago I knew it.

Vader: That happens.

Emperor: Man, that can't be. What was it? I don't get it. It's on the tip of my tongue. Ahhh, no, shit, I think it's gone...

Vader: Then it wasn't important at all...

Emperor: What else?

Vader: Okay. Lot of work. And you?

Emperor: Evil people are always well, you know? (I don't know if there's an english equivalent for this german saying)

Emperor: It just occurred to me. Where is the Deathstar?

Vader: It's broken.

Emperor: Yes. Now that you're saying it... I have to sleep over it. See you later...

Vader: ...Alligator... (I tried to find an suitable translation for the german farewell-phrase "Mach's gut" (Make it good), which is often accompanied with the silly reply "Mach's besser" (Make it better))...
