Bootylicious: See John Barrowman run around D.C. bare #assup

John Barrowman (a.k.a. Captain Jack Harkness) was in Washington, D.C. earlier this week for Awesome Con, D.C.’s annual celebration of all things comic book, sci-fi, superhero, fantasy, and pop culture.

While there, he and a couple of friends ran around town taking goofy pictures of themselves…

Are you supposed to sit in them @stephenamell @awesomecons #awesomecondc JB

Fun, right? Sure. But it’s the picture and video of John’s bare butt that’s got our attention.

The 51-year-old actor posted a photo of himself with his pants pulled down and his booty pointed upward, along with the caption: “#assup in Washington DC @awesomecons#awesomecondc chillin ass out.”

Then there was this video of him with his pants down “going commando” across a hotel hallway:
