Dominos is the pedo code for "Domination." Perhaps innocent and the true meaning of the word in this case? Not unless it immediately starts raining pennies from heaven.

A little background first.

David Letterman has returned to TV following his retirement in 2015, this time with Netflix. Six one-hour monthly episodes are planned to the tune of $2 million per show for Letterman, that will feature "in-depth conversations with extraordinary people..."

The first episode recently aired on January 13, 2018 with a surprise guest, Barack Obama, who had past appearances on Letterman's prior Late Night Show. Here is a clip from a May 4, 2015 Obama appearance where the two of them or about playing dominoes together during retirement.

On the first Netflix episode, Letterman replayed the video for Obama.

As a memory refresher, Letterman was no saint. In 2009 he revealed he had sexual relations with several employees of his show, all while being married to his current wife. He also revealed he had been blackmailed into giving a fake $2 million check due to a threat from Joe Halderman, former CBS (same network) news writer, director, and producer. Alderman threatened to produce a movie and write a book about his sexual misconduct. Haderman was jailed fgor extortion and served 5-months of his 6-month sentence. At the time, Letterman noted that he "could have easily been fired."
