As I lifted the side of the lorry
Twelve pigs tumbled into the quarry.
Thus the law they call ‘Sod’s’
Caused an outcome at odds
With the one I’d been hoping for. Sorry.

An apology ought generally to be accepted in good faith, but perhaps not when the speaker seeks to blame some external ‘law’ for his or her personal blunder. The Bible speaks of demonic possession in falling swine, of course: this might have made for a more winning excuse, though that story’s Animal Rights credentials are pretty flimsy too.
