Irish Mirror
 
> After living in the remote countryside of Ireland all his life, an old
> Irishman decided it was time to visit Dublin.
>
> In one of the stores, he picks up a mirror and looks into it. Not ever
> having seen a mirror before, he remarked at the image staring back at
> him.
>
> 'How 'bout that! he exclaims, 'Here's a picture of me Fadder.'
>
> He bought the mirror thinking it was a picture of his dad, but on the
> way home he remembered his wife didn't like his father, so he hung it
> in the shed, and every morning before leaving to go fishing, he would
> go there and look at it.
> > His wife began to get suspicious of his many trips to the shed. So, one
> day after her husband left, she went to the shed and found the mirror.
>
> As she looked into the glass, she fumed, 'So that's the ugly bitch he's
> running around with.'
