Visible crew/equipment: When Blackadder is called to the Queen's first practical joke and he says he didn't laugh because his head would fall off, the Queen says, "If you don't start soon, your head will fall off", the boom mike is visible above her head. (00:09:55)
Visible crew/equipment: When Edmund returns to his house and complains about the smell as he enters, the edge of the set is visible on the extreme right of the picture, just before the camera zooms in on him.






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.
