Jackie Burkhart: [Kelso arrives after his day at the Police Academy] Michael, you got another 'D' on a test? Isn't this your fourth 'D' in a row?
Michael Kelso: Yeah. It's just on the Penal Code stuff. "Criminals have the right to an attorney, criminals are innocent until proven guilty". Just crazy liberal gibberish.
Steven Hyde: [to Fez] What are you laughin' at?
Fez: He said 'Penal Code'.
Jackie Burkhart: Fez, it doesn't mean that. It's from the word 'penalty'. 'Penal'.
Steven Hyde: [Fez can't control his giggling] You're like a four-year-old. It's a legal term: 'Penal'.
Steven Hyde: [now Hyde is laughing, too] It's kinda funny.
Brooke: [Brooke comes in] Hey, guys. Hey, Michael, how'd your Penal Code test go?
Michael Kelso: [Hyde and Fez can't control their laughter as Kelso lies to impress Brooke] I did great. I got another 'B'.
Brooke: Oh, that's your fourth 'B' in a row! I'm so proud of you! Can I see it?
Michael Kelso: [suddenly on the spot] Uh... uh, you could, but, uh, I didn't write anything down, 'cause the test was, uh, oral.
Steven Hyde: [bursting with laughter] Oral test on the Penal Code!
