[BRIAN BLESSED]CURSE YOU!!! I HAD THINGS TO DO!!![/BRIAN BLESSED]
There is a version with canned laughter right as they go over the top. (I think it might be like that on the DVD of that episode on my complete boxed set). It is completely out of place. It’s not studio audience laughter, either - I just watched a show about the making of Blackadder and that scene wasn’t filmed in front of a studio audience.
As were watching the behind the scenes thing, my GF commented that she’d also seen a version of the final scene with canned laughter added, and how horrible it was - the op isn’t imagining it.
