So he has to go shopping with the missis, and she's trying on dresses, shoes, coats, handbags, shop after shop, can't find anything she likes.
After an hour or so of this she looks round and he's nowhere to be seen, so she calls his mobile.
Where the feck are you? she screams.
Ah, he says, well, do you remember before we got engaged, and we were walking down the high street and looked in a jeweller's window, and you liked that diamond ring, with the sapphire and pearl setting, but it cost too much?
And I promised you that if you married me, and I got a decent job, I'd buy you that ring? Do you remember that?
Yes, she coos, I do remember that, sweetheart....
Well, he says, I''m playing pool in the pub opposite that shop.
