Take THAT, "Tonight Show."

Joe Biden will appear on "Late Show with Stephen Colbert" the day before Donald Trump appears on "Tonight."

Colbert announced the booking -- a "get" pregnant with possibility -- on Twitter Tuesday: Per the tweet, "Wait, if he's here, who's vice presidenting the country?" 

Biden, who is weighing a run for the White House, will appear on the Sept. 10 edition.

Of note, John McCain on the Feb. 28, 2007 edition of "Late Show with David Letterman" announced that he would run for president.
