When Stephen Colbert and Bill O'Reilly — a.k.a. "Papa Bear" — get together, the result is almost always interesting and sometimes even surprising. Colbert seems to have a fixation on finding areas where the two of them agree — perhaps because his former Comedy Central character was kind of a mocking parody of O'Reilly and his brand of conservative punditry.

On Monday night, in a long and very worthwhile conversation about the massacre at a gay nightclub in Orlando, Colbert pressed O'Reilly on whether Donald Trump, by gloating about being right about the attack, is using it for political gain.

And O'Reilly, somewhat surprisingly, agreed.

COLBERT: What do you think of Donald Trump's response so far?

O'REILLY: Well, it's a political response.

COLBERT: It seems fairly self-congratulatory.

O'REILLY: Yes, it is. He's a politician. It shouldn't shock you. Trump has two things ...

COLBERT: ... There are other politicians who would not say, 'I appreciate the congrats' or 'I called it.' That's not political behavior; that's grandstanding.

(APPLAUSE)

O'REILLY: He wants to be president. He's using this terrorism issue to bolster his popularity.

COLBERT: So he's making a political tool out of a terror attack.

O'REILLY: That's what he's doing.

COLBERT: Is Hillary doing the same thing?

O'REILLY: I don't know.
