Complete circle on a golf hole

Is it possible for a golf ball to complete a circle on a golf hole?

The ball rolling around the rim of the hole once?

Technically, yes, because the golf ball experiences friction with the surface it travels on, so if it the golf ball starts performing circular motion because of the sloping part of the rim of the hole, it will eventually slow down and drop into the hole. However, I don't know whether this happens much in practice (I find golf quite boring to watch!).
Thanks from Loren

Wouldn't friction at the rim cause the ball to follow a non-circular path, one with varying height?

Unless the ball is sliding, the only friction at the rim is air. There would be a small amount of rolling resistance too. But, the biggest cause of a non-circular path is probably the dimples (and the ability to get the ball to reach the rim at just the right speed and angle, obviously). From above, it would look pretty circular though.
Traverse the rim is certainly possible, just not perfectly circular on a plane perpendicular to the rim.
Thanks from Benit13 and Loren
