Last month, a video of a guy pranking people while dressed as an evil clown has gotten about 15 million hits on YouTube. Now, part two is out. 
In the first one, he hid behind corners and started chasing people. That happens a lot in this one too, but there's one part where he waits for someone to walk part while he's digging a grave in the middle of the night in full clown regalia. As if being dressed as a clown isn't creepy enough by itself.
