[Blackadder is selling his house. Mr. And Mrs. Pants are looking around.]
Mrs. Pants: Strange smell.
Blackadder: Yes, that's the servant - he'll be gone.
Mr. Pants: You're really worked out your banter, haven't you?
Blackadder: No, not really. This is a different thing, it's spontaneous and it's called wit.
Blackadder: The path of my life is strewn with cowpats from the devil's own satanic herd!
Blackadder: This place stinks like a pair of armoured trousers after the Hundred Years War. Baldrick, have you been eating dung again?
Answer: The closest we ever get to knowing his first name is in series 3, when he claims it's "Sod Off". Blackadder asks him in series 3 where this came from, and he replies "Well, when I was a kid, living in the gutter, I'd go up to the other kids and say 'Hello, I'm Baldrick'. And they'd say, 'Yes, we know. Sod off, Baldrick.'" The S in this series is likely a reference to that, but it's not addressed, and given this Baldrick is clearly different from the series 3 Baldrick, we can't draw a direct link.
