Mayor Mitch Landrieu is proving quite the public scrapper. It was just a couple of weeks ago that Landrieu demanded sportscaster Chris Myers take back his oafish statements comparing Hurricane Katrina with the tragic floods in Nashville ... and now Landrieu is mixing it up publicly with London mayor Boris Johnson, who said yesterday "When you consider the huge exposure of British pension funds to BP, it starts to become a matter of national concern if a great British company is being continually beaten up on the airwaves."

This afternoon, Landrieu replied in a statement:

Quite frankly, I would suggest that London Mayor Boris Johnson park his anger at the waters’ edge and redirect it towards BP.

This is not America vs. Great Britain.

It’s people, families and their livelihoods versus a negligent corporation that is responsible for the loss of 11 lives and an oil spill that threatens our coast, our environment, and our economy. In fact, our entire way of life is at risk. So we are going to hold BP accountable for the damage done.

While Mayor Johnson is concerned about their pension funds, we're concerned about the lives and livelihoods of our people.

Don't get us wrong; New Orleans has been so maligned over the last few years that we like a mayor who'll put up his dukes when necessary -- but it would be a shame if this turned into a nasty, xenophobic little spat between the two countries that distracted from the real culprit: BP.

(That said, Johnson seems to have a habit of sticking his bespoke size 11s in his mouth; it wasn't long ago that he pissed off the entire city of Liverpool and had to travel there to apologize to the Liverpudlians. And once, on the campaign trail, he promised voters: "Voting Tory will cause your wife to have bigger breasts and increase your chances of owning a BMW M3.")
