The final question of the evening went to Lemon, who ended things appropriately, considering the tone and context of the evening. Per the CNN transcript:

Lemon: “Mr. President, you’ve been the big guy for six months now in the White House. Can you take us behind the scenes, something that was extraordinary or unusual that happened that stands out to you?”

Biden: “Yeah, ‘Mr. President, you didn’t close the door. … Mr. President, what the hell are you going out at this time for?'” (Laughter) “You know, it’s a wonderful honor. As you can tell, I hope I have very good manners, but I’m not very hung up on protocol.” (More laughter.)

The joke is on you, the American viewer or voter who simply wants the president to be challenged on the myriad of problems facing the country: Rising inflation (the president says his spending bills would reduce inflation), skyrocketing violent crime (Biden argues it’s a gun problem), a border that isn’t secure (with a record number of migrants entering the country this year, topping 1.1 million recently) and an an opioid crisis that is killing a record number of Americans (with a 30 percent jump in drug overdoses in 2020 over 2019).
