The very funny @TeaAndCopy excelled himself on Twitter today - as did a Sainsbury's employee by the name of David.
Because @TeaAndCopy - aka Marty Lawrence - tweeted @Sainsburys with a very silly fish pun... and they took the bait. As it were.
Check out the hilarious exchange which ensued, below. And if you know this David from Sainsbury's, do let us know, won't you? Come on, David - don't be koi!
