Ludwig had previously known Blackadder, Melchett and Queenie in various disguises. While explaining this to them, he briefly implies that he was disguised as someone (a smuggler, a shepherd and Queenie's horse, respectively) before revealing he was disguised as something else entirely (a waitress, Flossie the sheep and 'the handsome German stable boy' respectively)
Also done with his third disguise. Since the first two have Ludwig turn out to be someone (or something) Blackadder or Melchett slept with, Queenie's story initially appears to be the same... except he wasn't the horse Queenie liked to kiss, but the stableboy instead.
Germanic Efficiency: Exploited by Blackadder, who notes that Germans "are sticklers for efficiency." Without Ludwig himself around, his guards follow the same routine every day, allowing Blackadder to pinpoint when they're most vulnerable.
Groin Attack: How Blackadder and Melchett subdue their guards. "Trust me to get the hard one."
Hypocritical Humour: Blackadder scoffs at a kidnapping victim, saying anyone who is stupid enough to be tricked by someone saying "excuse me, mister" in a weird accent and hitting them over the head deserves to be kidnapped. Naturally, this exact thing happens to Blackadder about two seconds later.
Blackadder: Oh, God, how incredibly embarrassing.
It's All About Me: Faced with the threat of having to save either Blackadder (whom she's fancied) or Melchett (her sanest advisor), Queenie decides instead to throw a party, and "forget all about [them]".
Blackadder: Oh yes, we are proud of our comic serving wench voice, aren't we? Just because we can say 'zer' instead of 'sir' at social gatherings — the tedious little tird who puts on fancy voices. What else have you got in your astoundingly inventive repertoire, I wonder? I brilliant, drunk Glaswegian, no doubt? A hilarious black man — see you Jimmy, where am dat watty mellon? Oh fabulous! I can't wait for your side-splitting puff and that funny little croaky one who isn't anyone in particular, but is such a scream. And most of all, I like the one you do all the time — the fart in the German chamber pot standing in front of me.
Running Gag: The credits finally have Blackadder catch the balladeer, and kill him.
Shaped Like Itself: Apparently, Ludwig first met Queenie 'disguised' as 'The handsome German stable-boy'.
Spotting the Thread: How Blackadder is able to easily identify Ludwig at Queenie's party, when he's disguised as Nursie. For Ludwig is a master of disguise, and Nursie is a "sad, mad old woman with an udder fixation".
Tap on the Head: How Blackadder and Melchett are kidnapped. A German guard hits them over the head with a stick while they are distracted by another German guard.
