In the May/June 1981 issue of Billiards Digest, George Fels diagrammed what he titled "Funny Farm Break Shots".
In addition to the shots mentioned here, he also gave the standard one pocket break which sometimes pockets a corner ball. I think that same ball can be pocketed straight in by shooting at the middle ball of the opposite side of the rack. Exactly where, I don't know, but I think the shot can be adjusted by the contact on that ball.
George also mentioned making one of the two outside balls on the row of four simply by hitting the rack hard. George was skeptical of it working more than rarely and so am I.
