Exclusive I Give It a Year Blooper: Best Man Speech Disaster

It's highly likely that even if you haven't seen I Give It a Year , you've heard about that Best Man Speech.

But even funnier than that are the brilliant blooper outtakes.

We've got an exclusive look at the DVD and Blu-ray extras in this blooper clip showing Stephen Merchant getting his Best/Worst Man act into gear, and bringing Rose Byrne to helpless giggles with one of his guest shout-outs.

I Give It a Year is available to buy on DVD from 3 June 2013.
