Members of The Colbert Nation have been arting up Stephen's portrait for a few months now, but it appears the trend has moved beyond the portrait and onto the street. The proprietor of the Hey, It's Cat tumblr spotted this outstanding bit of street art today on 14th Street in New York, between 8th and 9th Avenues. Honestly, it's some of the best vandalism I've ever seen that doesn't involve an unchaste lady's phone number. (Click to enlarge)

The Colbert Report airs Monday through Thursday at 11:30/10:30c.
