As expected, President Barack Obama stopped in at the Late Show With David Letterman Monday evening to wish the popular CBS talk show host the best as he signs off for good after 33 years of serving as a TV personality and comedian.

The two men, who clearly have great respect and admiration for each other, talked everything from retirement hobbies to national issues. Obama even noted he could envision playing dominoes in his old age with Letterman.

"After a tough day at the office or coming home from work, knowing that you've been there to give us a little bit of joy and a little bit of laughter, it has meant so much," Obama said during his appearance. "You're part of all of us. You've given us a great gift and we love you."

It was the President's eighth appearance on the late night talk show, which will conclude its run on May 20. In his honor Letterman dedicated his nightly feature, the "Top 10" to Obama. The list for the night was "Top 10 Questions Dumb Guys Ask the President," and it didn't disappoint in terms of humor given one was "will you show us your birth certificate."

The question alludes to a controversial issue that has plagued Obama through both his administrations as some critics have claimed he did not have U.S. citizenship.

The mutual respect between the two men was evident throughout Obama's visit, with Letterman at one point acknowledging that Obama's sense of humor was pretty strong given his performance at the recent White House Correspondent's Dinner event.

"I'm a pretty funny guy," Obama noted in response.

Once the levity and jokes were over the two did discuss more somber topics, including the recent shooting of a Baltimore man by police, which set off a riots in the city.

The two also spoke about future retirement plans and downtime once they're both done with their current roles. Letterman mentioned he expects to take about a month's vacation. Obama said he and the First Lady are discussing potential volunteer work tied to helping investigate climate change and helping military families. He's also happy not be facing a new political campaign.

"It does feel good not to have to be on the stump," Obama said.
