Paddy Murphy suspects that Mrs Murphy is doing the jiggerypokery with Declan O'Toole from next door.
Deciding to catch her at it, Paddy tells her he's working late when he leaves in the morning.
That evening Paddy was hiding in the bushes over the road from his house, and sure enough, shortly after dark young Declan hopped over the fence and disappeared into Paddy's house.
Poor old Paddy paced up and down, muttering darkly to himself, for a few minutes to give the treacherous pair time to get busy. Finally, unable to stand it any longer, he stomped across the road to the house and on into the bedroom. Sure enough, there they were, in flagrante delecto!
"You cheatin' feckin' trollop" shouted the outraged Paddy. Dashing to the wardrobe, Paddy pulls out his old double barrelled shotgun, ****s the hammers and puts the muzzle under his chin.
At this development, Mrs Murphy starts laughing uproariously. 
"Go on, laugh it up" yelled Paddy, your bloody next ya cow."
