It was Donut who put the sign and rope, was he?

Well I hope they're at least well versed with the proper procedure.

Hahah, Black Adder is classic!

I love that episode.

G: “We appear to have crawled into an area marked with mushrooms.”
E: (patiently) “What do those symbols denote?”
G: “Pfff... that we’re in a field of mushrooms?”
E: “Lieutenant, that is a military map. It is unlikely to list interesting flora and fungi. Look at the key and you’ll see those mushrooms aren’t for picking.”
G: “Oh, you’re quite right, sir. It says ‘mine’... So... these mushrooms must belong to whoever made the map.”
E: “Either that, or we’re in the middle of a minefield.”
B: “Oh dear...”
G: “So, he owns the field as well!”
