Come on now - you all knew that Guinness is all sorts of spoiled so this next part shouldn't come as too much of a surprise to you....
A couple weeks ago we went out for a really fantastic sushi dinner with a friend of ours and while it was fantastic we unfortunately ordered too much. None of us were willing to do "sushi leftovers" but since it was just the fish (no rice etc.) we figured as long as we gave it to him pretty quickly that we'd see if Guinness might enjoy it.... and oh boy did he!!!
Here's some video of him chowing down!
And he most definitely licked the "plate" clean when he was done!
