Carla gives Dr. Cox Josh's biopsy results. Cox barely glances at the folder before telling Josh's parents that the kid has "hairy-cell leukemia." Dr. Cox says it's treatable, and he's willing to talk to Josh about it. The parents reveal that they've decided not to tell Josh that he has cancer. Cox is stunned.
Elliot, Janitor, and Ted plot to figure out Kelso's age. Ted suggests lining up a hundred people from age 1 to 100, and then figuring out where Kelso fits in. Janitor suggests that they cut off Kelso's legs and count the rings. Elliot realizes she's not going to get any help from these two, until Janitor points out that he has keys to the personnel files.
Rex is still following Hooch around, and Hooch threatens to burn him. Carla laughs that Hooch is crazy. Cox still can't believe that Josh's parents won't tell him about his disease, especially since Josh is more mature than most of the doctors in the hospital. JD runs in with a giant clipboard, and Cox snarks, "Exhibit A. Through Z." JD takes out a giant pencil and pretends to take notes on Cox's advice. Cox wants JD to write this down: "I, John Dorian, am a ridiculous, thirty-two year old overgrown infant." Cox reminds JD that two weeks ago, he was asking everyone if he needed to grow up, and Cox thought maybe becoming a father would be an epiphany. Cox concludes with sarcarsm, "Way to go. We are all super-proud of you."
Turks waits outside in his giant lab coat. Kelso walks out and confirms that he hired Turk as a surgeon, and then says, "Way to go, Bob." JD walks out and says he's not going to play with Turk today, because it's time for them to grow up.
Elliot and Janitor check Kelso's file and find out that Kelso is turning 65.
Dr. Cox goes into Josh's room and fills him in on his leukemia. WOW! Doctors are always pulling this shit on TV, but I have to imagine it would result in a GIANT lawsuit. Whether or not you were a giant doctor.
Ted tells Dr. Cox that Josh's parents are livid. Well, I would guess so. Nearby, Elliot tells Kelso that she has a secret. My favorite moment of the episode is what Kelso says next: "What has two thumbs, a funny voice, and doesn't give a crap? [points thumbs at himself and speaks in funny voice] Bob Kelso! I added the funny voice to keep it fresh."Elliot says she has 65 reasons why she should give a crap. The elevator doors open and Janitor blurts, "You're old!" He continues as the elevator doors closes, "Yes! I've been saying that every time the doors open for the last two hours, and I finally got my man. [Puts his hand up for a high five] Give it up! Little something! Still got time! [Doors close] We'll do it later!"
