"Welcome to This World" is a song by PRIMUS that was played in the Season Four episode, "The Tooth Fairy Tats 2000".


After reading extensively into existentialism and philosophical theory, Kyle Broflovski some how ascends to an elevated plane of existence. This song is played over a montage of Kyle's ascension and eventual return to normality.


  • The song is a mix of two tracks from the album, "Pork Soda" and "Welcome to This World".
