How does a newly lame-duck mayor cap off his first day back in the public eye?

With a little self-deprecation: Mayor Vincent C. Gray stopped by the WTTG-TV news set late Thursday to participate in an homage to late-night legend David Letterman, who is retiring next year: Gray read a Top 10 list of potential replacements for the CBS host. Spoiler alert: Gray himself takes top honors.

“‘Cause I’d be free at that point,” he said, before demonstrating a textbook Letterman-esque cue-card fling.

Another priceless moment: No. 6.

“One word,” the mayor said. “Kim-yay.”

“Mr. Mayor, do you know who Kimye is?” asked anchor Shawn Yancy.

“I think I do — Kanye West?” the mayor said. “I quit while I’m ahead.”

Earlier in the evening — hours after he was noncommittal about delivering a public endorsement of her nomination — Gray made his first public appearance with the woman who beat him Tuesday, Democratic nominee Muriel Bowser, at a Leadership Greater Washington event held at Georgetown’s Fairmont Hotel. According to Post columnist Bob McCartney, both were invited on stage without prior notice by the event’s host, WJLA-TV’s Rebecca Cooper. Both complied:
