Jimmy Fallon used his Tonight Show monologue to poke fun at former President Joe Biden's forthcoming memoir, joking that Kamala Harris had written its ending. The jibe fits a broader pattern of late-night hosts mining material from Biden's post-presidency and his exit from the 2024 race, keeping the former president a recurring target of topical comedy even after leaving office.

The article offers little detail beyond the joke itself, noting only that Biden's memoir is due for release and that Fallon delivered the quip on a recent broadcast of the "Tonight Show". No further specifics on the book's title, contents or publication date were included in the report.
