Answer

I do not know the context.  I speculate that it is a derivative of an old English expression "silly goose"  which includes expressions like "you silly goose" or " I'm a silly goose" or "he's acting like a silly goose."  Such references to a goose in English are usually pointing out that you did something silly or embarrassing and you are admitting that it was wrong and/or a mistake.

Answer

It comes from the expression "silly as a goose" or "a silly goose." Note that "silly" is much milder than "stupid."
