WATCH > Justin Bieber Tries 'Cone-ing': Funny or Dumb?

In recent interviews, Justin Bieber has said he's trying to set aside time to both "be a kid" and "grow up."

This must have been one of his "being a kid" days.

Now that Bieber has a driver's license, he's free to participate in "cone-ing," that ridiculous trend someone came up with to replace "planking," a more dangerous ridiculous trend.

Because that's what 17-year-old guys do these days.

If you haven't been following, good for you! But "cone-ing" is basically the practice of ordering an ice cream cone at a drive-thru and picking it up upside down, by the ice cream.

It's kind of like a prank. Only, you're the only one who has to clean anything up.

And the Biebs didn't stop there. He also attempts to set a new trend.

Here's what you do: 1) Order a drink from any fast food chain. 2) Try to return it at a different fast food chain. 3) Complain until people start honking. 4) Drive away.

Genius, right?

Maybe, when his music career is finished, he can make a collection of Bieber Virals, and film himself participating in the latest fads, like cinnamon swallowing and cup stacking. (Isn't that basically how he became famous in the first place?)
