He was surprised mid-conversation by Leno, who drove up on a golf cart.

Oh my God, Jay Leno!

Can I give you a hug?

After a quick hug, Leno told the interns, Ross was my favorite intern.

We had a lot of them, but he was the most annoying.

That was the fun part.

Can you believe, Jay, its been 23 years since I started on your show?

And look at at us, we look great!

In response, Leno teased, Well, I look great, anyway.

He then added, No, no, you look good.

I cannot believe 23 years has gone by, Mathews said.

To which Mathews joked, I have a mortgage, Jay.

Well, we enjoyed having you.

I always liked you because you were kind.

I think you started in the mail room.

But you just had a funny personality, he said.

I thought, Well, this kids got something.

The pair then reminisced over sending Mathews to theOceans Elevenpremiere.

I said, Well, how about that new, annoying guy, Ross the intern?

I think he might be funny, He teased as Mathews laughed.

And you did a great job and then it kind of leap-frogged from there.
