The best lies are ones immediately picked up by a co-conspiritor without acknowledgement, for the porpoises of winding up others.
Sitting on the tube with a mate new to Mordor, we went through the as-then closed-for-the-duration Mornington Crescent.

"It's always closed" said newbie.

"Yeah" replied other mate, "Richard Branson's bought it - he's going to build a Virgin Megastore over it and advertise it as the first shop in London to have it's own tube station"

"Aye" I agreed, "They're going to rename it "Virgin Central". Blummin' capitalist bastards, raping our history and culture in pursuit of the Yankee dollar ..."

Several years later, we were delighted to go out with (by now not-so) new-to-London mate, and overhear him instructing a girl about this, and when she questioned how come it was open now, about how the deal had fallen through so he'd sold it back to the London Transport Network at a massive loss.

Bonus click for use of the word 'porpoises'.
