Jimmy Fallon thinks he knows how to scare Donald Trump.

In his Tuesday night monologue, “The Tonight Show” host looked ahead to next week’s presidential debate between the former president and Democratic nominee Kamala Harris.

“Both Harris and Trump are spending hours each day preparing. Harris is working on various comebacks, while Trump is up to 80 hot dogs in 10 minutes,” Fallon quipped.

“Apparently in her debate prep, Harris is focusing on ways to rattle Trump,” he added. “Yep, she wants to rattle Trump. Right now she’s deciding whether to wear a jacket that says IRS or FBI.”

As the November election nears, Trump is still battling various legal entanglements. The sentencing in his criminal hush money case, where he was found guilty of falsifying business documents, is scheduled for Sept. 18.
