Commenting on the current dust-up between Rand Paul and Chris Christie over pork-barrel spending, Joe Scarborough has managed to insult both combatants.

And in warning Paul not to pick a fight with Christie, Scarborough cited a saying by his grandmother to the effect that you should never fight with a "pig," because "you both get dirty and the pig likes it." Scarborough was careful to suggest that in comparing Christie to a "pig" he wasn't alluding to the Jersey governor's girth. OK. View the video here.
