DSP or signal/image/data processing jokes
An airplane is leaving Warsaw (the capital of Poland), and gets caught in a terrible winter storm. The plane rolls, pitches and yaws. The crew is expecting the plane to crash or break up at any time. But one DSP student suddenly stands up and asks some passengers on the right aisle to move across the plane. Passengers are reluctant but the student insists. “Hurry, our fate depends on your move.” Most passengers quickly leap to the other side, and suddenly the plane stops shaking. The pilot, who had a DSP degree too,  enjoys calming everybody:


  "Thank you for the Poles who have moved to the left-half of the plane for stability."
