From Legends of Tomorrow:
John Constantine, explaining why he had difficulty locating a timeship lost in the vortex, exclaims, “My business card says ‘Master of the Dark Arts,’ not ‘Doctor ruddy What’s-his-face’!”
To which the other two characters in the scene reply “Who?” and “Who.”
Constantine responds, “Exactly.”
