The somewhat indolent father Traugott Wurster looks after his six sons while his wife works in a butcher's shop. One day, when Traugott falls into a mysterious prolonged sleep, mother Wurster is forced to give the children to relatives. Markus is sent to the stuffy Uncle Theodor, who turns into a childhood friend under his influence. Mother Wurster also "rents" the sleeping Traugott to a furniture store, which uses him to advertise mattresses in the shop window.
Unfortunately the movie Mein Onkel Theodor oder Wie man viel Geld im Schlaf verdient is not yet available on Disney Plus.
