David Letterman may not have a clue who he's talking to these days, but that can make for some funny exchanges, as we saw last night with Ryan Lochte.

While slightly more restrained than the Philly anchors who LOST IT after interviewing the Olympic swimmer, Dave seemed baffled by the same thing:

Why does Ryan Lochte have a reality show again?

It's a fair question, and the What Would Ryan Lochte Do? star attempts to explain it as best as you can hope from a man (and show) of such substance.

Watch a portion of their exchange below:

Anyone who saw the Super Bowl in February also saw Cameron Diaz feed popcorn to Alex Rodriguez in a hilariously awkward, PDA-packed display.

Promoting her flick Bad Teacher, the star gave us the inside scoop on the snacky sideshow to David Letterman on The Late Show Tuesday night.

She then reenacted the incident with the cantankerous host ...

"We were sitting there watching the game, and I was eating, and I was getting down to, like, the last couple pieces of popcorn," Diaz recalled.

"All of a sudden, I see [Alex's] hand coming in. Anybody who knows me does not put a hand in my food, especially this close to my mouth."

But ... "I said, 'What are you ... ?' And then I went, 'You know what? I love you too much, I'm going to give it to you. You deserve it.'" Aww/barf.

As for their relationship, Diaz put an end to any A-Rod breakup rumors, calling him her boyfriend, in spite of his overzealous snacking and everything.

Sounds like a keeper.
