Who? Ed Begley Jr., William Daniels, Stephen Furst and Eric Laneuville turned up in a 2002 episode of NBC's "Scrubs." Why? The four "St. Elsewhere" docs are helped by JD (Zach Braff) after being stuck with a needle filled with the blood of a patient with Hepatitis A. Like "Scrubs," "St. Elsewhere" revolved around young medical interns learning the ins and outs of the job.
