Students Execute Perfect April Fools Day Prank [VIDEO]

This is how you, brilliantly, use somebody's own rule, to your advantage.

April Fools Day is obviously the best day of the year for practical jokes and these students came up with a brilliant prank for their professor. Before you watch the video, know the professor has one rule... if your phone rings during class, you must answer it, on SPEAKERPHONE.

Well played, students.
