So this is about to get freaky...

David Brock and James Alefantis sold a house to Scott & Luz Driscoll for 2.25 million back in 2013: http://www.pressreader.com/usa/the-washington-post/20130613/282741994358283 (link dead already, anyone got an archive please) - further proof: https://image.isu.pub/130920155905-670c3c030807fd29e0eb188eb277ecb3/jpg/page_106.jpg (full original article: https://issuu.com/washingtonlife/docs/0913_digital/106))

Scott T. Driscoll passed away a year before Comet Ping Pong opens, and 8 years before he buys the property with his wife from James & David: http://www.masterdeathfile.pub-dat.org/Deceased/Index/153747065

[History -- Founding and Carole Greenwood -- Comet Ping Pong was originally founded by James Alefantis and Carole Greenwood in 2006. Source: Wikipedia]

Through a google search, we find Luz and Scott Driscoll are linked to this address: blockshopper.com/dc/washington-county-dc/washington-kalorama/property/25190282/2310-california-street-nw (page doesn't load for me)

Which is the same address David Brock and James Alefantis purchased back in 2007: http://washingtonlife.com/issues/march-2007/real-estate-news/index.php - "In Kalorama, 2310 California Street, N.W, now belongs to bestselling author David Brock and his partner, restaurateur James Alefantis."

With database searches of James Alefantis, it confirms this property as his as well as other properties listed under that name:

1. 6513 Brawner ST Mc Lean, VA 22101

2. 2310 California ST NW Washington, DC 20008-1637

3. 1536 Swann ST NW Washington, DC 20009

4. 1352 Bradley DR Harrisonburg, VA 22801

5. 5037 Connecticut AVE NW Washington, DC 20008

Lets keep digging boys.
