Gustafsson was born in Goteborg, Sweden. He studied at the Calle Flygares Theater School in Stockholm to become an actor.  But before his debut as an actor, he had already debuted in 2005 as a stand-up comedian at Bungy Comedy, a Swedish club for stand-up beginners. In 2006 he enrolled at Standup Star, a stand-up school, where among others, Özz Nûjen and Jakob Öqvist, two of the most well-known comedians in Sweden, have attended.

As of 2008, his most notable appearance was in Melodifestivalen 2008, the Swedish selections for the Eurovision Song Contest. For example, he sang a song to Kristian Luuk's (the host) girlfriend Carina Berg. In his song he declared his love for her. Afterward, Berg said that she had to hide her cheeks so people couldn't see that she was blushing.
