Alexander Armstrong is the latest celebrity to get Midnight Game Show treatment on Michael McIntyre's Big Show, the only gameshow where if you snooze you lose.

The Pointless presenter and Classic FM DJ and his lovely wife Anna are woken in the night by Michael McIntyre who has some unusual surprises in store for him.

McIntyre said in the run-up to the broadcast: "Alexander Armstrong was wonderful because he has got a lovely house and he is so sweet and so funny.  There is some hilarious moments in his gameshow including a ‘posh-off’ with Jamie Laing, there are also two sheep in his bedroom!"

Midnight Game Show has been hilarious viewing in recent weeks. Comedian Chris Ramsey was a particular highlight when he was awoken by McIntyre and had to do some UFC cage-fighting. Ramsey also revealed on social media something a lot of viewers must have wondered. What happens if you have an erection when you are woken up with cameras in the room? Ramsey said he was far too scared by the shock of the experience to have a stiffy.

Alexander Armstrong, who first made his name as half of comedy double act Armstrong and Miller, will also be appearing at the Stratford Literary Festival later this year. Details here.

The show also features singer Olly Murs and Stacey Dooley handing over her mobile phone for some Send To All Fun. And this week there is a pair of Unexpected Stars of the Show, Gabriella and Jasmine Tuicicia from Carnforth, who get brilliantly pranked by Michael McIntyre heavily disguised in a track suit wig, glasses and funny facial hair. If they seem familiar that might be because they appeared on The Voice Kids on ITV1 over Christmas, singing with Black Eyed Peas superstar will.i.am.
