Isaiah Washington (b. 1963) is an actor who played Dr. Preston Burke on Grey's Anatomy from 2005 until 2007. In 2005, Washington (and his wife Jenisa) was interviewed by Pepe the King Prawn at the Flightplan premiere in From the Balcony episode 8.
Pepe asks the fictional doctor about a problem that he's having with his prostate; Washington seems thrown by the question.
