Frasier: 10 Guests Stars You Forgot Were On The Show
1. Zooey Deschanel
Before New Girl, Zooey Deschanel had a role as Roz’s estranged cousin Jen who managed to irk every character in the show except KACL radio station manager Kenny, who she has a brief romantic encounter with. The 20-year-old's party atmosphere is too much for Roz in the 2002 episode Kissing Cousin.
Jen is demanding, opinionated and even critical of Frasier's show. Even Roz is eventually annoyed by her own cousin.
Deschanel is almost unrecognisable without the long brown hair she's had since, but did rise to prominence a year later as a blonde in the movie Elf.
The fourth episode of Season 10, Kissing Cousin is often regarded as one of the worst. Luckily Deschanel has pursued a successful career in film, television and music since.
