President Barack Obama may not believe that corporations are people, but Oscar Mayer wants the commander-in-chief to know that his recent public condemnation of a certain condiment stirred the hearts of its fleet of mobile hot dogs.

“After hearing about the president’s affiliation for mustard-only hot dogs, the Midwest-based Oscar Mayer Wienermobile team has decided to institute a new rule,” the Wienermobile team said in a statement. “If and when one of the six Wienermobile vehicles is in the greater Washington D.C. area, out of respect to the president’s hot dog preferences, the hot dog on wheels must feature an added mustard decal decoration. Never ketchup. The rule is effective immediately and will survive throughout the current term.”

The patriotically-themed marketing move comes after Obama’s appearance on Anthony Bourdain's food and travel show, "Parts Unknown," in which the president vocalized his disdain for ketchup on hot dogs, a nod to his Chicago roots.

“Is ketchup on a hot dog ever acceptable?” Bourdain asked during the show's season premiere Sunday.

“No,” the president replied frankly. “It's not acceptable past the age of 8."

“My hot dog question might have been diplomatically problematic for a first-term president. He answered without hesitation -- like a Chicagoan,” Bourdain wrote of his recent bun cha meal with the president in Vietnam.

Bourdain also recently rattled off his favorite places to eat in Chicago during a Reddit AMAA.
