A man is in the supermarket checkouts one saturday afternoon. He starts to hear the screams of disgruntled children and the the screams of an even more disgruntled mum in shell suit and trainers who is in the process of shouting and swearing at her kids, berating them and calling them names. The man quite upset at the way these children are being treated turns to the shell suit clad woman and asks
"Awww twins, how old are they?"
The woman looking a little perplexed starts another volley of insults and answers the man
"Twins? Twins? What the F makes you think they are f'ing twins, are you blind or f'ing stupid?"
To which the man replies
"Because I can't imagine anybody wanting to have sex with you twice"!
