Blackadder: I remember Massingbird's most famous case - the Case of the Bloody Knife. A man was found next to a murdered body. He had the knife in his hand, thirteen witnesses had seen him stab the victim and when the police arrived he said 'I'm glad I killed the bastard.' Massingbird not only got him off, he got hom knighted in the New Year's Honours list, and the relatives of the victim had to pay to get the blood washed out of his jacket.
Back and Forth: When Blackadder first goes into the time machine to get the items from Baldrick, and the door goes up, you can see a crew member pushing the door closed, wearing a red shirt.
There are in fact two versions of the bonfire scene. Although most countries use the intended censored version (where somebody coughs right as Edmund says the F word) there are a few US editions where you can hear him swearing uninterrupted.
