However, other results may be reached; on rare occasions, Tom triumphs, usually when Jerry becomes the aggressor or when he crosses some sort of line (the best example of which occurs in The Million Dollar Cat where, after finding out that Tom's newly acquired wealth will be taken away if he harms any animal, including a mouse, he torments Tom until Tom finally loses his temper and attacks him).
