Kelso: Easiest money I ever made. They paid me fifty bucks for my underpants navy.
Hyde: You mean your cordoroy commandos?
Fez: Yeah, your team from the inseam.
Eric: Your Battlepants Gallactica.

Eric: I'm sorry Kelso... Because I hear there's this clinic in Madison that will pay you for your manly donations.
Kelso: Manly donations? Ooh I can do that, I'm pretty good at that.
Red: Thanks son... I love you.
Eric: W-What did you say?
Red: I said, I love you.
Kelso: Good news! my boys are back in friendly hands.
Donna: Ironically, that's just where they started their journey.
Nurse Ruth: I'm sorry miss, but I can't give it to you. The donor himself is the only one who has legal rights over this specimen.
Jackie: Fine! Michael, you get them. You're the only one who has rights over your special men.
(Kitty and Eric are eating breakfast)
Eric: Mom, was dad abducted by aliens and replaced by an identical creature programmed to love?
Kitty: Honey, this is breakfast. Don't ask me things.
Eric: He told me he loved me.
Kitty: Your father? No!
Jackie: Oh, that's okay. Kelsos never call. They're like dogs. They're cute, but they can't work a phone.
Casey: I just got this thing, where a lot of times I just don't show up. I don't know what to do about it.
Donna: How about showing up?
Casey: I guess I can give that a shot .
Donna: So, this will never happen again?
Casey: No, I'm pretty sure it wil happen again...
Fez: It's so good to have a girlfriend on Valentine's Day.
Kelso: Yeah, it definitely increases your chances of getting your 'fun stuff' touched.
Eric: Well, ...(looking at his crotch) sorry 'fun stuff!' Looks like it's just you and me this year. ...Unless... (looks at Donna)
Donna (glancing at Eric's crotch): Sorry, 'fun stuff.'
(talking about saying 'I love you')
Red: Alright, stop right there. There are only a few times in life when it's acceptable for a man to use that phrase. When he's drunk, when he's dying, or when he's in big trouble and that's the only way out. Which usually means he's drunk.
Eric: Colonel Mustard called; he said 'get a clue.'
Colonel Mustard is one of the characters in the Parker Brothers/Hasbro board game Clue.
Kelso: No, Farrah was on Carson last night, I should be good to go.
Notably, Farrah Fawcett was a guest on The Tonight Show only once, and that was in May, 1992.
