Having not quite recovered from a rather fruity night out at Noel Gallagher's gig, he told us: "I'm writing a second series of Bad Education now.
"We have quite a lot of surprises in store. My character Alfie gets gang-banged. He doesn't actually – but he might do.
"I don't have any celeb cameos yet, but I'm going to make some up anyway because I want viewers of Digital Spy to watch it.
"Matt Smith and Benedict Cumberbatch appear in one episode. They get off with each other. Sherlock bums Doctor Who."
Currently starring in Fresh Meat as posh prat JP, he revealed there will be a third series on the way: "It's not really fresh anymore. It's stale now."
The 24-year-old told us about his most student-worthy night out, saying: "I've been to 'Traffic light' parties where you have to go as red, amber or green – depending on if you want to pull or not.
"I went in black so I could follow the reds home.
"But I'm really grown up now and only drink Chianti. I'm lying. I love Jägerbombs. I think Bombjägers are better - do a switcharoo. Fill up a glass with Jägermeister and pop in a little shot of Red Bull."
When we ask him if he'd consider appearing in the next Inbetweeners films with his Fresh Meat co-star Joe Thomas, his minor obsession with a former TOWIE star rears its meaty head.
He told us with about as much genuineness as an Essex tan: "Only if I could appear with Mark Wright. He's a very handsome chap.
"I'm going to buy his calendar. I might do one of my own. I'd go full-frontal. It would be x-rated."
With a successful career and a bucket load of upper crust swagger, he must get inundated with groupies? He told us: "I tend to do the sending of the rude pics.
"I'm like comedy's answer to Ashley Cole."
We ask him about the rumours that he's been asked to star in a new sitcom with James Blunt written by Made In Chelsea and I'm A Celeb's Hugo Taylor.
"I read that," he said, unimpressed. "I'm almost certain I won't be doing that. I'm not holding out for the call…
"I've watched MIC but I'm almost certain I won't be doing that. I was very shocked. If he wants to do it, then good luck to him. I won't be in it though."
We ask him about I'm a Celebrity and he said: "I've watched a little bit. Hmm, Nadine Dorries.
"It's an interesting tactic isn't it, to go and try to talk about the serious issue of abortion whilst you're eating kangaroo testicles. I don't know. It's probably a silly move."
He is, however, into The X Factor and said: "I love Rylan. I met him recently and went over to him and had a picture. I turned into a fan girl. But I like him. He gets it. He is what he is.
"He knows what the competition is, and he's just going to do it. I don't really vote on X Factor, but if I was, I'd do him.
"And I like James Arthur. He really means everything he says and sings. He always looks very upset..."
We can't help but ask him what he thinks of Alex Reid's supposed 'sex dungeon'.
He said: "I've done drag before – my name was Vera Gwendolin and it was bloody brilliant. I'd definitely do it again.
"I'm not sure how a sex dungeon works. I don't know whether you buy things for it or it just comes about naturally. I imagine you have to have bars on the windows for it to constitute a sex dungeon."
We try to pry about his old school pal Robert Pattinson and what skills Jack would bring to the role.
He said: "I haven't seen the new Twilight – I wouldn't want to take that role up anyway. Edward Cullen is 800 years old. Bella is 17. It's pretty weird."
