there's an idea there, 'get one over on those stinkin' lyin' journalists' but he's just such a black hole of charisma that he expresses this to the guy, presumably a supporter who takes pride in what he makes & sells which amounts to an insult.

if he'd just procured bad food and fed it to journalists on purpose to disrespect them, that would be mischief the CHUDS would lap up, we'd probably have a laugh ourselves. but instead of actually doing it he just says the idea out loud as a 'joke' disrespecting the deli owner.
