-I wanted to ask you about something.
There was a thing on a --
I think it was a BuzzFeed show or something
where they have a new technology
where they can swap two human being's faces.
And they used the technology on us weirdly.
I don't know why.
-There was a Nicolas Cage film about that, I think.
-Yes, there was.
They actually put your face on my body.
And this is -- -Wow!
-There's the original. And then there's --
-Oh, no. They put -- Wow.
That is a horrific thing to do.
I will say this, your chin
is carrying a lot of the work there for both of us.
That computer has very wisely said,
"Let's take Fallon's general --
Let's just put his glasses on Fallon's face."
-But wait. We actually have a video, as well.
And I wanted to show you if you haven't seen it.
Look at the video.
-♪ Bringin' '88 back ♪
♪ Bring the hooks in, where the bass at? ♪
♪ Champagne spillin', you should taste that ♪
-Oh, no.
[ Cheers and applause ]
Oh, no. -It's the real deal.
-Nobody wants that. -That happened.
-Yeah, sure, that's a lot of -- that's a lot of --
That's very impressive technology that could be used
for a great number of good things.
I think deep down, we all know it's going to get used for porn.
-Really? -Yes, Jimmy. Yes.
Everything gets used for porn.
Every major breakthrough is used for porn, first and last.
That is going to -- I promise.
There's going to be a lot of porn films with you in now...
and a lot of very bad porn films with me in them.
-Oh, my gosh.
-And as for our combined mutants, I don't know.
I'm happy to publicly license our offspring.
That's right. I'm happy to --
It can be used in pornography if it's tasteful.
-Don't say that.
No, you can't speak for my face-swapped body.
-I can speak for half of it.
Jimmy doesn't want to be associated with anything.
Just a nice, romantic scene. Set it up.
-Tasteful. -That's right.
We'll keep it classy.
Pan to the fireplace.
And then, you know, let the [bleep] start.
-All right.
-What? What? -You kept it classy.
-What, NBC? What?
Oh, that's right. Different rules.
-Yeah, exactly. Different rules here at NBC.
Season five of your show that's on HBO --
-Did you just pivot there with an edit point, Jimmy?
I think you did.
I think you did. I think you did.
-We'll leave that in. I've got time to fill, man.
I'd leave that in.
But, really, though, let's talk about your show on HBO,
because you just finished season five.
-Yes, we did. Congratulations.
-Thank you. Thank you very much.
-It's one of the best shows on television at this moment.
If you have not seen "Last Leek Tonight,"
you do such a great job on that show.
It is always informative, very topical,
but also very thorough.
And you do these amazing pieces,
and I'm a giant fan of you and the crew over there.
-Thanks. We're so proud of our staff.
They work incredibly hard.
And our favorite thing that we ever get to do --
Obviously, the long, very complicated stories are very satisfying.
But doing really dumb [bleep] with HBO's money
is the thing that makes me happiest.
Just irresponsibly using their resources
is my quiet, consistent joy.
So this year -- We buy a lot of dumb things.
This year, Russell Crowe had a divorce auction.
-I remember this. -And so we bought --
We bought his jock strap from the 2005 movie "Cinderella Man."
-He was actually auctioning that off?
-That's right. He was auctioning it off.
So we bought it and we sent it to a Blockbuster in Alaska
to try and keep it open, like a kind of museum to movies.
Didn't work. Anyway, we heard nothing --
-Nobody wanted to go to the Blockbuster Video
to see his jock strap?
-Obviously, I'm different from the people of Alaska.
-Yeah, you can't speak for them. -That would be a magnet to me.
But I'd heard nothing from Russell Crowe about this.
I presumed he was very angry.
Until -- Until he did the most spectacular thing.
'Cause he used the money to fund and construct,
in Australia Zoo in Sydney,
the John Oliver Koala Chlamydia Ward.
And it might be the single-best practical joke
I've ever been on the receiving end of.
It's the perfect joke in many ways.
You got the sign, right? He did this.
-It's real. -He did this. In Australia.
[ Applause ]
It's -- It's incredible. -It's genius.
-I am genuinely impressed
with Russell Crowe's ability to land a joke.
For the rest of my life, especially in Australia,
my name will be synonymous with koala chlamydia.
-If it wasn't already.
-That's a shutdown joke. That's a dunk.
That's a windmill dunk. -Yeah, it is.
Good job, Russell Crowe. -Good job. Good job, Russell.
-Good job, John Oliver. John Oliver, everybody.
New episodes of "Last Week Tonight"
will be on HBO in February.
