Onkel X is forced to take up his old profession of window cleaning once more, but ends up bribing some local boys to do the work. Arend Vogel is suffering from mice in the attic and Cousin Herbert happens to bring a long a toy mouse 'that only scares women folk'.

Arend Vogel has been lying in bed for a week because Hansje has dumped him. He finally storms out of the house upon finding out that Hansje has got a new boyfriend, Jos. At that moment, Dr. Kruimel comes to check up on Vogel.

When Onkel X arrives back from the states, he is being shadowed by a suspicious man who claims to be from interpol. The man is investigating the effect of the Knots' family secret - the pink paint. Arend Vogel is trying his hand at another way of influencing people: by hypnosis.

Grandpa is sure he's won 250.000 guilders in the lottery, but can't remember where he hid his ticket.
