Operators of several websites that admire the Cleveland congressmen are urging readers to complain to Pizza Hut. They're not mad about Kucinich being linked to pepperoni despite his meat aversion, or being linked to chain pizza despite his anti-corporate rhetoric. It's the UFO reference that's given them indigestion.

"I am going to encourage all Kucinich supporters to boycott your restaurant until you change your "debate" advertising," wrote the operator of a website called Dandelionsalad. "That was a low blow to a viable, electable presidential candidate. Consider the word OUT! I also think Pizza Hut should publicly apologize to the Congressman!"

The world's largest pizza chain hasn't received many complaints about the politically-oriented ad which began airing nationally last night to kick-off a new $5 pizza promotion, according to Pizza Hut Public Relations Director Jennifer Little.

She called the ad a "lighthearted way to tie into the important topic of the economy," and said Kucinich's UFO remarks were used because they were among the most memorable comments uttered in any of the presidential debates.

"We found humor in his comment, so we included it and words from all the candidates in the ad for our new Pizza Mia product," Little said. "We also want to remind people to vote in this important election, whomever they support."
