How did Penelope plan to find out if she was truly with odusseus?

Penelope devised a clever test to determine if the man claiming to be Odysseus was truly her husband. She instructed her servants to move their marriage bed, which only she and Odysseus knew was built to be immovable, with one leg made from a living olive tree. When Odysseus reacted with anger and disbelief at the suggestion of moving the bed, it confirmed his identity to Penelope, as only the real Odysseus would know this intimate detail.
