I used to have an Indian Runner drake who made us laugh every day. To impress his girl, he'd charge after us...as long as our backs were turned. If we turned to face him, he'd stop & look away, almost as if he were whistling nonchalantly. Then we'd turn our heads away & he'd pretend to charge again. He'd do this for hours. We called him "little big man." He never made contact with us, just the fake chasing.
