Burger King is so confident about its new plant-based offerings...

The bagel guy is pulling no punches — or low blows — as he prepares to step into the ring.

Chris Morgan, the Long Island bagel shop customer whose rant about dating woes went viral, has signed up for a celebrity boxing match, according to TMZ.

The 5-foot-nothing star of Bagel Boss meltdown fame spoke to the site after signing contracts with fighting promoter Damon Feldman to step in the ring on Sept. 7 in Atlantic City.

“I don’t need no training, I’m prepared,” the scrappy bagel fan said about the bout, which is likely to be quite short.

The promoter said there was a “possibility” he would fight Antoine Dodson, another viral video star after his reaction to a home intruder in Alabama in 2010.

“I’m just naturally tough — I’ll whoop his ass,” Morgan bragged. “If he thinks he’s gonna win, fuggedaboutit!”

Saying that his talent was “getting possessed,” Morgan showed off a one-two combination for TMZ’s camera.

“Sit back and wait,” he said, going into a pretend rant.

Morgan became a viral sensation with his wild rant about getting knocked back by women on dating sites because of his height, lashing out at a female customer before he was tackled by a larger man in the store.

“Everywhere I go I get the same f–king smirk with the biting lip,” he had shouted, later telling The Post his outrage was sparked by “belittlement.”
