Phil is all in on project hatch-the-duck-eggs, even building a whole habitat for them — no one else is as enthused about this project and Lily is the only one suckered into helping him. Claire, meanwhile, is nervous about pitching her new closet ideas to Jay and his creative team, and for good reason it seems. And, Gloria and Manny help each other out with their respective “crushes,” while Cameron develops an unhealthy attachment to the frat guys renting their upstairs unit.

When J.D. (Zach Braff) accidentally gets stuck with a needle that may have been infected with hepatitis, he starts to shy away from dealing with his sicker patients. Meanwhile, he and Elliot (Sarah Chalke) are forced to deal with four doctors (guest stars Ed Begley, Jr., William Daniels, Stephen Furst and Eric Laneuville of "St. Elsewhere") who become ill while attending a local medical convention. Elsewhere, Turk (Donald Faison) pays a high price when he goes to Dr. Cox (John C. McGinley) to help him get in shape. Ken Jenkins and Judy Reyes also star.

As the team tracks an elusive, chameleonlike killer, NCIS Assistant Director Granger (Miguel Ferrer) critiques every step of the investigation.
