Charlie: I think you guys are playing games with me, and I don't like it.
Roy: Now, wait a minute. We're not playing games. We don't play games with the equipment...
Captain Stanley: Wait, hold on. C'mon everybody, look we're all on the same side here, aren't we?
Charlie: I wonder.
Captain Stanley: Charlie, why can't we put the squad in the shop and have us a reserve vehicle here?
Charlie: No, no, Hank. Not until I'm 100% sure that I can't fix it. If there's anything wrong with it. This coffee stinks. [Leaves the room.]
Captain Stanley: You guys playing some kind of joke on him?
John: We didn't make the coffee!
Captain Stanley: Not the coffee, you twit, the squad.
Roy: Cap, there's something wrong with that squad out there.
Captain Stanley: [sigh.] All right, if you say so... I made the coffee.
Roy: Well, what did your doctor say?
Captain Stanley: Well, actually, I haven't talked to a doctor yet.
Roy: Then how do you know it's arthritis?
Captain Stanley: What else could I have?
Roy: I don't know, but instead of expecting the worst, you might just try to get the facts. Let me call Dr. Brackett. I'll arrange an examination.
Captain Stanley: No, no, no!
Roy: What do you mean, no? Why not?
Captain Stanley: I can't leave here. I'm on duty.
Roy: I'll make the appointment for tomorrow.
Captain Stanley: No, I don't want to impose on Dr. Brackett.
Roy: You're not gonna impose on Dr. Brackett. That's his job. That's why I'm giving him a call.
Captain Stanley: No. Look, Roy, look. What if it isn't arthritis? Then I'd feel silly bothering him.
Roy: If it is arthritis, wouldn't you like to know about it?
Captain Stanley: That's hard news to take.
Roy: Well, you've already given yourself the worst possible news.
Captain Stanley: Yeah, but I could be wrong.
Roy: Look, wouldn't you like to know one way or another? At least you'll stop worrying yourself to death over it.
Captain Stanley: You'd worry too, if you had arthritis.
Roy: Maybe you don't!
Captain Stanley: Then why see a doctor?
[Henry, the dog who is never ever off the couch, whimpers.]
Johnny: [Talking to Henry, while typing on the typewriter.] Sorry. Didn't mean to disturb you. Acting kinda uppity aren't you? I may put you in the script. Yeah. A dog that does nothing. [Henry whimpers.] Just sits there. People like that, y'know. A schleppy dog. You'll schlep out on stage and schleep on the couch. Dumb dog! [Henry whimpers.] Making me feel guilty. Why don't you howl or something?
Charlie: Well, as long as I'm here, let me take a look at it.
Captain Stanley: Oh, I see you guys got some help.
Charlie: Hi, Hank.
Johnny: Not really. We fixed it ourselves.
Charlie: These two prima donnas here don't believe in calling in a repair. They wanna do my job for me.
Roy: It was just a loose connection there.
Charlie: Now they're telling me I'm not needed around here.
Johnny: No, Charlie, we're not telling you that at all.
Charlie: What's this? What... What IS this? Adhesive tape here?
Roy: Well, there was a bare connection there.
Charlie: You thought it was gonna bleed to death, so you put a bandage on her, right?
Roy: Look, we were at the hospital and we just put it on just to get us back here to the station.
Charlie: You got tape?
Johnny: Yeah. [Gives Charlie proper tape.]
Charlie: If it wasn't for me, you guys would probably give an IV to the gas line and debrillitate [sic] the battery.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
