Walker Harnde,a sophomore at The University of North Carolina School of the Arts now holds the world's record for highest-pitched whistle.  The note that broke the record was a B7, which is the B just below the high C on a piano... that's pretty darn high.

Check out the video of this amazing feat below.  And if you think you can whistle higher, tune into The Boris & Robyn Show tomorrow morning to see how you measure up with against our morning show!
