It started out on the Washing Post
The Washington Post called Jason Bourn-illa Soft Serve, until they found out his name was Zach Burroughs. Then BuzzFeed got a hold of this photo . . .
. . . and the photoshopping mania began. Posters on BuzzFeed renamed him The Thundersnow Ice Cream-Cone Guy. A D.C. local newstation added their own Thundersnow Ice Cream-Cone Guy photos. Zach just wanted an Ice Cream-Cone, and before he knew it, he was an Internet Sensation as well as the first meme of 2011.
The Washington Post tracked him down and Interviewed him:
The Washington Post: Next question. "Are you a time-traveling tourist from a place where global warming has made January a month hot enough to wear that outfit and want ice cream, or are you from the southern hemisphere where it's summer now?"
Zach Burroughs: I'm just from around the area. But you might see me next summer with my heavy coat on and a hot chocolate.
Zach says "The Snow Identity" is his favorite.
