No, the friend bit is that Callum and Morris were both at MKD. Its a play on a well known, reenacted bit of Inbetweeners.
I'm aware of, but have never seen Inbetweeners, so now seeing the clip I'd say it's a clever bit of marketing and shows the players who took part in a very positive light. I thought it was funny and well pitched.
you gotta watch the 3 series, they're mint if you don't mind crude comedy, also 2 films though 2nd one was a bit of a let down
