S3, E14: Dr. Cox is all smiles when his ex-brother-in-law Ben returns, Christa Miller Lawrence, Tara Reid and Brendan Fraser Guest Star. -- Danni (guest star Tara Reid) and Jordan's (guest star Christa Miller Lawrence) brother, Ben (guest star Brendan Fraser) returns from traveling the world, a trip he's been on since his leukemia went into remission. When Dr. Cox learns he hasn't seen a doctor since he left, he recruits J.D. (Zach Braff) to do a thorough work up. Unfortunately, forcing J.D. to drop his other patients to run tests on Ben is a decision Dr. Cox soon regrets. Meanwhile, Elliot's (Sarah Chalke) concern about a bunion on her foot leads to the revelation that Carla (Judy Reyes) has been hiding something from Turk (Donald Faison). Ken Jenkins and Neil Flynn also star.
