On Rosh Hashanah (Jewish New Year), there is a ceremony called Tashlich.

Jews traditionally go to a body of water such as the ocean, a stream or a river to pray and throw in breadcrumbs.  This symbolizes throwing away one's sins which the fish devour.  Occasionally, people ask what kinds of breadcrumbs should be thrown.  Here are suggestions for breads which may be most appropriate for specific sins and misbehaviors:
