John Wilson on how to become a TV sensation

Day after day, the host of HBO's "How To with John Wilson" roams New York City filming thousands of moments to put in his show.  

"Sunday Morning" contributor Kelefa Sanneh accompanied Wilson to a dumpster. Wilson said, "Let's see what the NYPD throws out."

"You must have hours and hours of dumpster footage," said Sanneh.
