The comedian asked a series of questions on “The Tonight Show” Thursday and enlisted old clips of the president and his predecessor to get his answers.
It included the following exchanges:
Fallon: Mr. Biden, when did you start preparing for next week’s debate?
Biden: That was back in 1871, I think.
Fallon: Mr. Trump, over to you. Have you been prepping for the debate?
Trump: Not even a little bit!
Fallon: Now, the debate stage won’t have any chairs, so you’ll both be standing for over 90 minutes. Mr. Trump, how long before you’ll need a break?
Trump: In 3 minutes.
Fallon: Mr. Biden, how about you?
Biden: In 3 seconds.
Fallon: Mr. Biden, just to confirm, you’re sticking with the same vice president?
Biden: Um, what’s her name again, Karen?
Fallon: Kamala. Kamala Harris. And Mr. Trump, are you planning to announce your running mate before the debate, or will they remain anonymous?
Trump: An anomoloussss.
