"Old Saying Describes Actions for Misbehavior" by Susan Pearl

"Your goose is cooked".

"He (she) cooked his own goose when he (she)…."

This old saying has nothing to do with a goose or with cooking.  It has everything to do with a person's reputation or actions that take away from others having a favorable opinion of that person.  When confronted with the evidence of the misdeed the person may be told- "Your goose is cooked".  When things are brought into the light and seen for what they are- the decision is made for dismissal, or for retribution of the offense or maybe an end to the friendship or relationship.  At any rate, it means that something is "over"...and no more will the person be allowed to repeat the offense.  For instance, an example would be that "so and so" will no longer be able to do the collection basket at Sunday service because he was caught taking some of the money.  He cooked his own goose when he took the money from the collection basket.  He has been dismissed from that duty.  His goose is cooked when it comes to handling the collection basket money from now on.  The trust in him for having that responsibility is over.
