The Stephen Colbert era on late night TV has begun. After taking the stage to enthusiastic applause, Colbert opened with a stand-up monologue in which he observed, "If I knew you were going to do that, I'd have come out months ago."

Colbert then sat behind his desk and cracked a set of topical jokes, using TV-news-style graphics that would not have been out of place on "The Colbert Report."

Not surprisingly, many of these jokes were about Donald Trump, who is the political surprise of the summer by leading in polls for the 2016 GOP presidential nomination. Noting that Trump has been favorably received by white supremacists, Colbert said this was "amazing" because "Trump's not even white — he's more Oompa-Loompa American."

Then he got serious for a while, interviewing Jeb Bush, the former governor of Florida (and brother of President George W. Bush, the subject of a merciless roast that Colbert performed at the 2006 White House Correspondents' Association dinner). The new host asked Bush straightforward policy questions about education and gun control.

But then came many humorous flourishes. Colbert teasingly asked Bush about his use of an exclamation point in his campaign poster ("It connotes excitement," Bush explained) and referred to remarks by his mother, Barbara, in which she said the country has "had enough Bushes" in the White House ("She was just joking," Bush said). Colbert also offered him new talking points to use in presidential debates that the host said sounded "Trumpier." Among these upgraded lines that he had Bush recite were "I will build a wall between the United States and Iran."

Colbert also interviewed George Clooney in which he gave the actor a belated wedding gift to congratulate him on his 2014 marriage to his wife, Amal, a human-rights lawyer. Clooney opened a box from Tiffany & Co. to find a paperweight with the inscription "I don't know you."

Months after denying their relationship was over, Jon Hamm and Jennifer Westfeldt are splitting up. Hamm and Westfeldt released a statement through publicist Annett Wolf that "with great sadness" they were separating after 18 years. The couple, who never married, said they would "continue to be supportive of each other in every way possible." The statement first appeared on the website of People magazine.
