Comic-Con is no stranger to celebrities.
But while many people at this year's NYCC were lining up for autographs from the cast of Marvel's Daredevil and waiting in line for panels like the Firefly reunion, they didn't realize a LITERAL AVENGER WAS SECRETLY IN THEIR PRESENCE THE WHOLE TIME.
Unbeknowest to the crowds around them, Mark Ruffalo and his son walked the floor of NYCC, enjoying the festivities in anonymity thanks to his hideous mask.
And elsewhere, upcoming Joker Jared Leto did the same.
Ruffalo even periscoped his adventures, rubbing salt in the wound.

While Leto documented the experience on Snapchat and Twitter, posing with NYCC attendees who were cosplaying as The Joker and Harley Quinn.
Moral of the story: Never trust a man in a mask. Always suspect he's a movie star.
He had no idea. :) #NYCC2015
