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.

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

The angels were portrayed by Rita Polster, Kirsti Wallasvaara, Ritva Vepsä and Merja Tammi.

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.
