Koeputkiaikuinen ja Simon enkelit (The Test-tube Adult and Simo's Angels) is a 1979 Finnish comedy film directed, written and starring Spede Pasanen, along with the typical comic-cast of Simo Salminen, Vesa-Matti Loiri, Tapio Hämäläinen and Olavi Ahonen.

Mathematician Mauno Mutikainen is accidentally pronounced dead as a result of an operation where a splinter is being removed from his finger, which he got by scratching his head.

The gangsters Luigi and Teuvo attempt to unsuccessfully to kidnap Jyrä and/or Mutikainen, thinking they are the same person.

Simo himself is constantly beset by terrible luck, being imprisoned and having his briefcase stolen by the gangsters as the movie goes on.

Vesa-Matti Loiri, Simo Salminen, Olavi Ahonen and Tapio Hämäläinen had only recently become nationally renowned for their involvement in Spede's Uuno Turhapuro franchise.
