Int. House as man unlocks and steps through the door smartly dressed
1st Man: (Calling) Hey babe, i'm home.
1st Man moves into the kitchen to find his wife having sex with another man
1st Man: What the?!
Woman: (seeing her husband) Andrew!
1st Man: What the hell's going on? Who's...wait did you just call me Andrew?
2nd Man: Who's this guy? I thought your husband was in a coma?
Woman: (to 2nd man) It's not what you think Dave!
2nd Man: Well, It looks like...I'm not called Dave.
Woman hesitates
A third male voice is heard from upstairs: Is everything ok? I heard shouting
Woman: Everything's fine Mike, it's the Tv
Pause
3rd Man: Who's Mike?
3rd man enters in towel
1st Man: (to woman) Listen Jenny, I want to know what's going on. Now.
Woman: I'm not called Jenny
Awkward pause
1st Man: Well this is going to take a while. Tea anyone?
END
Cheers for all your comments and 'Steve by any other name' for a punchline.
