Well, to start off with I would wait for him to return from work, say "I think we need to talk" then start wailing like a banshee "How could you? Am I not good enough?" Then start screaming hysterically how he is low life scum and of course he is going to deny an affair. Then run up stairs and start throwing his things out of the window, set on to all his shirts and trousers with a pair of scissors. Once he is an emotional quivering wreck say "Hah Fooled yer! I was only joking" and give him a big smooch!
Does that answer your question? :o)
