From the L.A. Times:
The men explained the situation to the police, who then knocked on World Peace's door to verify their story.
"At first when I seen the police, I was like, 'What the hell is going on?'' World Peace said. "I just got finished watching 'Zero Dark Thirty' or whatever that movie is. I'm like, 'I'm dreaming, I'm dreaming. Is there a terrorist in the building? Do y'all need my help?'"
After a brief conversation with the police, World Peace put on his Cookie Monster pajamas and accompanied them outside.
There is context to all that, but it's much better to imagine sleepwalking World Peace out there fighting terrorists in his Cookie Monster pajamas. In any case, there's no such thing as a bad Metta World Peace story, and today is no exception. For more on why the police showed up and what happened from there, this L.A. Times piece is highly recommended.
For instance: Did you know Metta World Peace owns a production company?
Now you do!
