Donald Trump insists he’s not weird, but he keeps throwing himself under the bus with his own words and actions.

A prime example of that occurred at Tuesday night’s presidential debate, Jimmy Fallon noted Wednesday on “The Tonight Show.”

“Everyone thought [Vice President Kamala] Harris seemed really prepared, while Trump was like my homework was eaten by a dog, that was eaten by people in Ohio,” the comedian cracked.

“There were so many wild moments last night, but the craziest was when Trump pushed a baseless conspiracy theory about immigrants in Ohio,” he added. “Looks like ‘Operation: I’m Not Weird’ isn’t going well.”

After Harris baited Trump with a swipe at his rally crowds, the Republican nominee veered off course, repeating a racist lie that Haitian immigrants are eating Americans’ pets in an Ohio town. “In Springfield, they’re eating the dogs ... they’re eating the cats,” he raved.

Democrats have taken to calling Republicans “weird,” a line of attack that has clearly gotten under Trump’s skin.
