Are there any things that's, like, left out of your show

that we could help you with here on our show tonight?

-You know, I've been so busy.

And I've just been being spread so thin,

I haven't had a chance to properly thank everyone

I want to thank, and I know on "The Tonight Show,"

you usually do this at the end of the week.

But I was hoping that maybe I could do some thank-you cards

or thank-you notes. -I mean, we could do --

We can do this. [ Cheers and applause ]

-Can I do that? Can I do that?

-You want to sit there? -Can I sit there?

-Yeah, you can sit -- -Can you sit here?

I'm down. Let's do it. -You're part of the family now.

You can do it. You can use the desk.

[ Cheers and applause ]

-Alright.

-You can use this.

-Is this a first?

-Yeah, actually, it feels weird sitting in this.

-Are you nervous? -I am. I'm totally nervous.

-Don't worry. I think I know what to do.

James, can I have some thank-you music, please? 00:00:42.642 --> 00:00:44.143 line:0% ♪♪

-Oh, my gosh. You do know what you're doing.

-Thank you, NBC, for being the only network

where a woman could have a show after midnight

that allows her to keep her clothes on.

[ Cheers and applause ]

-That's exactly right.

-I did my research. I did my research.

-I don't put the cards in the envelopes. This is great.

-Thank you, "A Little Late," for being a good name

for a late-night talk show and a great name for a pregnancy test.

[ Laughter and applause ]

-Yeah. It's an awful name actually, yeah.

"A Little Late."

-Thank you, Jimmy and Seth,

for basically being the opening acts to my show every night.

I don't say this about a lot of people,

but I've got a feeling that you guys

are really gonna break through and make it big some day.

-Oh, my gosh! [ Cheers and applause ]

I feel like -- I feel like --

You're almost too comfortable here.
