It started innocently enough. “Kid Reporters” Jaylah and Ryan were interviewing members of the New York Knicks at their practice facility, asking the very tall men kid-friendly questions, like can they spell “supercalifragilisticexpialidocious.” (Not surprisingly, they couldn’t.)

Then, the intrepid duo went in for the kill, asking the players if they would sing some Justin Bieber for the camera. You knew this was coming.

Some of the players refused, but others — well, let’s just say that Knick forward Jared Jeffries and center Tyson Chandler displayed some pretty telltale symptoms of the dreaded “Bieber fever.” Check it out below.
