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))...
