The carpenter suspected his wife was unfaithful. He hid under the bed and waited.
The wife thought he was gone and invited her lover to come.
Then his wife heard him under the bed, so she screamed, "Hands off, villain!" Her lover was confused. "A goddess told me my husband would die unless I brought a man into my bed. So, you got in; now get out!"
"Such devotion!" yelled the carpenter joyfully. "Thank you both!"
He then stood up under the bed, lifting the bed on his back, and carried the lovers on the bed all around the village.
