Meyer is acting like a cock doing mating season. This leads to a lengthy discussion about birdsong between the tenants of the house. Clausen suggest that they go on a bird watching trip. Olsen takes the role as chairman of planning, Meyer signs up to be the samaritan, and Egon will provide the liquid refreshments.

Egon, being very interested in international relations, is studying French and ends up falling in love with his teacher, or maybe the teacher made him interested in those relations to begin with. After having a fight, Karla kicks him out and he ends up staying with Emma in the backroom at Rottehullet.

Clausen, being an old scout, has received the honour of substituting for the local scouts troop leader and Olsen has won a tent in the scouts' lottery. The two set off to test out the tent and their skills on the embankment, well laden with drinks.

Meyer is in love with the graceful and well dressed Mrs. Holmberg and spends a lot of money on meeting her lifestyle. The new couple is enjoying an expensive dinner at Rottehullet, when a strange man named Freddy shows up and claims to be Mrs. Holmberg's fiancée.

Karla and Egon want to buy a house, but they have very different vision for what their new home should look like, and what it should cost.

The result of a nationwide survey shows that Olsen's son Willian, is one of the country's most gifted children.
