WOW…Anons found a Washington Post article from 2007 claiming that Tucker Carlson was a “regular” at Comet Ping Pong.

Yes, THAT Comet Ping Pong.

>The appeal of such a venue is broad. Families appreciate the joint for the obvious (be warned: the sounds of restless little ones can easily outmuscle Dean Martin and Rosemary Clooney on the soundtrack), and the stargazing can be prime. Among the VIP regulars are ballet director Septime Webre and talking head Tucker Carlson, but even Donald Rumsfeld has dropped by for a pie.
