Congratulations

S4, E3: Adam's arrives home to a 'Congratulations' banner hanging in the hallway, and a super excited mum and dad. They're celebrating Adam's first award - for writing the music to a commercial. But Adam's celebration soon turns sour when Jonny turns up with an American girl he met in Las Vegas. Lisa is a lovely, sparky girl, but when mum learns that Jonny and Lisa got secretly married in Vegas, mum goes mad. An awkward evening ensues with mum trying her best to be as polite as possible to Jonny's new wife. But it soon becomes clear that Jonny and Lisa know absolutely nothing about each other.
