Finnish

Finnish is the official language of Finland.
In "The Psychic Vortex" (S3E12), Sheldon decides to learn Finnish because he needs to kill time while loading the new operating system on his computer and had already disinfected the kitchen and the bathroom. Several Finnish words appear in this episode (such as "sisään", come in).
