Two mates meet in the pub;

‘’What’s wrong, mate. You’ve got a face like a slapped arse.’’

‘’It’s the wife. She wants sex every day. She has done for the past couple of years’’

‘’You lucky git. Bit of a nympho, eh. What’s wrong with that?’’

‘’Every time she orgasms she headbutts me’’

‘’The price you pay I suppose’’

‘’I just heard her on the phone to her friend and she admitted she’s been faking orgasms for years’
