<p>During graduation, a few kids handed our principal objects, like used tissues, charcoal, etc. during the handshake. Since there was a pretty continuous stream of students walking across the stage to get handshakes, the principal had to put them in his pocket.</p>
<p>One kid put Vaseline on his hand before going up onstage, but the principal just switched to his left hand. </p>
<p>No one noticed this during the ceremony, though. You could only see it if you looked closely at the video.</p>
