On October 28th, 2010, police in Berlin, Germany, arrested Travie McCoy and an unnamed accomplice for tagging one of the last remnants of the historic Berlin Wall. How did they know that McCoy was their graffiti culprit? Well, it seems that the rapper/Gym Class Heroes frontman had not only tweeted his intent to hit the Wall beforehand, but also later tweeted a pic of his finished artwork. (The fact that he'd written "Travie McCoy" in blue-bubble lettering was an additional tip-off.) McCoy and friend were eventually released on $2,000 bond.
