Okay, for those who don't understand this, way back in May the fabulous Derren Brown tweeted "Watching the poor sheep in the fields we're passing and wondering how much happier they were in the wild."
When I saw that I laughed for ages.
Then a couple of my fellow Derren fans (Dickbrains but we didn't know back then xD) kept tweeting "Jungle Sheep!" And that is now an inside joke between us to this day :3
