David Letterman and Amy Poehler recently shared a kiss on his CBS talk series "The Late Show."

The one-second smooch occurred on Tuesday's episode, after the 41-year-old actress talked about how she tried to plant a smooch on Vice President Joe Biden while he was filming a guest spot on her NBC show "Parks and Recreation." Letterman, 65, then announced a clip from the series would be played.

"Oh, I thought you were going to go in for a kiss, okay," Poehler said.

She leaned in slightly and he then grabbed her arm gently and planted one on her.

"Whooo!" she said, clapping and rubbing her hands together.

"Thank you," he said.

"Thank you," she said.

"Thank you," he repeated.

"Thank YOU," she replied, drinking from a "Late Show" mug and rubbing some of the beverage on her neck as if it were perfume.

"Tell that to your little buddies back there at NBC," said Letterman, who has for years openly mocked Jay Leno, who hosts the network's competing late-night series "The Tonight Show."

Biden appeared on an episode of "Parks and Recreation" that aired on November 15. Poehler's character, Leslie Pope, is in love with the U.S. leader.

"I was really excited to meet him as well," she told Letterman. "We did a couple of takes and then at the very end, just for the heck of it, I just went in for a kiss."

"He was so great. I think he's used to a lot of crazy people because he just kind of handled it really ... You learn a lot about yourself and the other person when you go in for a kiss," she said.

Letterman had also planted a kiss on a seemingly unsuspecting Regis Philbin on ABC's "Live! with Regis and Kelly" almost exactly one year ago, in November 2011, just before Philbin left the daytime series.

On Tuesday's episode of "The Late Show," Poehler also talked about her and actor Will Arnett's two sons, Archie, 4, and Abel, 2. The actress and her husband announced in September they plan to separate after 9 years of marriage. She told Letterman that her eldest son has been inquiring about male and female anatomies.

Poehler also discussed her and fellow "SNL" alum Tina Fey's upcoming stint co-hosting the 70th Annual Golden Globe Awards, which will air on January 13.

"We were asked and we said yes. I'm excited -- the Golden Globes are kinda loosey-goosey. There's not as much song and dance you have to do, I think. But it is kind of a cool night, where television and film are honored together, so it's this rare opportunity where all the beautiful, symmetrical people of film get to hang out with us rat-faced TV people, us dirty TV people."

"That's right - guilty on that charge," Letterman joked.
