A twist on "Man Bites Dog"?

Grocery shopping here in London is always an adventure... I never quite know what new product lies around the corner. This morning, at Waitrose, here was the shelf before us. I know that sometimes my level of humour is a bit 'elementary', (or, if you prefer the more erudite terms, 'Rabelaisian', or indeed'scatelogical'). And even though the phrase 'meat balls' evokes no giggles from me, somehow 'fish balls' does make me snigger. But it was the placement of 'Fish Balls' and 'Tuna Bites' along side eachother that was the kicker.... yes... a interesting shift on "Man Bites Dog" :-) I don't know whether to feel more sorry for the Fish or the Tuna!
