We find out Dr. Kelso's real age is 65.

This is Hooch's first appearence since the season four finale, "My Changing Ways".
Janitor: (elevator opens) You're old! Yes! I've been saying that when the door opens for the last two hours, and I finally got my man! (As the elevator door starts to close) Come on, give it up, a little something. (elevator's almost closed) Still got time. (door closes) We'll do it later!
Dr. Kelso: What has two thumbs, a funny voice and doesn't give a crap? (weird voice) Bob Kelso! ...I added the funny voice to keep it fresh.
Dr. Cox: Who cares about losing your childhood? I damn sure didn't.
J.D.: Yeah, because your parents were violently abusive alcoholics. Not that there's anything wrong with that. It was probably very exciting.
Turk: Ok, we're both off in an hour, so I planned our plan.
J.D.: You just used the same word twice in the same sentence.
Turk: You just did too.
J.D.: That is so weird that I didn't even notice that I did that. Same word, four times, one sentence!
Turk: Dude, you're in the zone.
J.D.: I feel it.
J.D.: It's just that when I have Sam I'm so busy, you know? We're up at 6, I feed him, I bathe him, then it's poopy time, then it's his poopy time.
Turk: I'm off. Uh, you wanna go shoot some hoops?
J.D.: I have a baby strapped to my chest.
Turk: So I just won't pass to you.
J.D.: Cool, same as always.
J.D.'s narration: No matter how old you are you should never forget the importance of childhood. Whether it's letting your kid hold on to his... or holding on to your own; Because everything happens so fast, it all can slip away before you know it.
J.D.'s narration: They say that the truth hurts; and sometimes it does. But sometimes it's just surprising, and other times the truth just wasn't supposed to be heard in the first place.
Ted: Sir, I got you a power drill. I know you wanted one for your hobby shop.
Dr. Kelso: The Janitor already gave me one. Nobody likes a copycat, Ted.
Ted: So what do I do with this?
Janitor: Ooh! Thanks.
Hooch: (to the interns who are following him) I'm about to use the toilet right now. So I hope you all are happy with the order that you're standing in. Because if you follow me in there, that is the order that I'm going to kill you. (to himself) Oh yeah! Today is gonna be a good day. Yes it is!
Elliot: So, how do we find out Kelso's age?
Ted: We pay a hundred people, age one to a hundred, line them all up and see which one Kelso looks like.
Janitor: I say, we cut off Kelso's legs, and we count the rings.
Elliot: That only works on trees.
Janitor: And puppets.
Ted: Kelso makes my life hell. Now, I know usually I cave, but there's no way I'm going to his party.
Elliot: I understand, Ted.
Ted: Fine, I'll go. Damned!
Elliot: Oh my god, is that a smile?
Dr. Kelso: Well, it's like last year, when the safety brake failed on Enid's wheelchair, and she started rolling toward our pool. I told myself: "Bob, it's already too late to stop it so you might as well sit back and enjoy it."
Ted: Chicks, ah? They're all soft and cuddly, but you'll never get to be with one.
