All Wrong

Sammy and Malsie from Dromore had been married for forty years, when Sammy came home one day all excited.
'Maisie, Maisie, he said, I've just discovered we've been making love wrong all these years!'
'What d'ye mean, Sammy?' said Maisie.
'You're supposed to moan when we're doing it, Maisie.'
So that night they were lying in bed in a state of intimacy, and Sammy said: 'Right Maisie, start moanin' now.'
'Sammy, that ceiling could do wi' a new coat of paint,' said Maisie.
