It still seems shocking that David Letterman announced his plans to retire from hosting CBS' Late Show with David Letterman last year.

Celebrities React To David Letterman's Retirement Announcement

It was only recently that his retirement began. On May 20 Letterman concluded his run with the hit CBS late night talk show.

Letterman's Late Show first began airing in August 1993 and Letterman has been part of thousands of episodes. Now that it has concluded, Letterman made sure to hook up his now former employees with awesome custom-made letterman jackets, according to TMZ.

This final Late Show with David Letterman gift included his iconic, "Thank you and good night" phrase adorning the front of each jacket.

Fur days after his final episode of the Late Show aired he was seen out enjoying his retirement at the Indianapolis 500, according to Indianapolis Star.

Letterman is an avid fan of the Indy 500 and is even a co-owner of team Rahal Letterman Lanigan Racing.

The Hollywood Reporter revealed that the recent retiree was honored at the racing event since his racing team put a smiling caricature with gaps between the teeth of his face and the hashtag "#thanksdave" on driver Oriol Servia's yellow car for the big race.

SB Nation reporter Jordan Bianchi shared a photo of Servia's car on Twitter to show off the tribute to Letterman.

"With everything that's happened, it's the highlight of my career," Letterman told the entertainment site.

"It's crazy it's the Indianapolis 500. Regrettable my face, but also my name on that car. It's just delightful," he added.

Perhaps the 68-year-old will become more involved with the team now that he no longer has his late night talk show.

Aside from this outing, Letterman seems to be avoiding the limelight.
