Blue in the face
Also is the name of an interesting movie directed by Wayne Wang and Paul Auster in 1995. It stars Harvey Keitel, Madonna, Giancarlo Esposito, Roseanne, Michael J. Fox, Jared Harris, Lily Tomlin, Mira Sorvino, Lou Reed, Mel Gorham, and Jim Jarmusch.
Blue in the Face was filmed over a five-day period as a follow-up to Wang's 1995 movie, 'Smoke'. During production of 'Smoke', Keitel and the others ad-libbed scenes in-character between takes and a sequel was made using this improvised material. (From Wikipedia)
