Want to see a bunch of actors messing up, cracking up and occasionally being really rather potty-mouthed? Then take a little look at the Parks and Recreation season four gag reel (or "series four outtakes", as we call it in Blighty.)
Never heard of the show before? Tsk - do keep up! It's s a US sitcom, starring Amy Poehler as a mid-level bureaucrat in the parks department of a fictional town in Indiana. It's a bit like a cross between The Office and Veep. See? That's sold it to you, hasn't it?
Anyway, we strongly suggest you get on with watching the outtakes - sorry, gag reel - before it gets pulled for being too rude.
Mind you, if you're particularly partial to watching people swear on US TV, you may also like this hilarious supercut of ALL THE SHOUTING in The Newsroom...
