Nitz's fake ID shows him as being Han Solo from New York.
While Nitz eventually learns to drink so as to "not look like a jerk in front of Kimmy," Jesse's and Cal's original insistence that Nitz has to drink while in a bar is quite wrong. Many bars will provide free non-alcoholic beverages, respecting the rights of any designated drivers that may be on the premises.
Rocko: (Sees Nitz with a sign that says "Will puke for booze) Nitz. How did you end up like this?
Nitz: It was you Rocko, okay? I learned it from you.
Rocko: Ugh, you drink this crap. What is it?
Asian: Run Beerzilla.
(Nitz stares into the bar, seeing Kimmy hugging two guys)
Nitz: She's ... a drunken hug fiend! And I can't do anything but watch.
Homeless Man: Please stop talking to yourself, you're scaring me. I AM ELECTRIC JESUS!
(In Rocko's sobriety induced dream )
Bartender: Here's that giant bottle of whiskey the president wanted you to drink, Rocko!
Rocko: Uh-uh, sober!
Bartender #2: Rocko, yho have to drink this giant martini or I'll be eaten by wolves!
Rocko: Uh-uh, sober!
(Bartender get's attacked by wolves)
(Small Asian man offers Rocko a bowl of noodles)
Rocko: Mm-mm soba!
Rocko: ( in church, still in diaper ) Bobby Whiskey, I renounce you, in front of God and everybody. From this day on, I will never drink again!
(image of Bobby Whiskey appears at the alter)
Bobby Whiskey: No, Rocko! Why hast though forsaken me?!
( Rocko falls backwards )
Priest: C'mon now, laddie. Let's be getting you some pants, that's a good boy. ( takes a shot from flask and offers it to Rocko)
Rocko: (entering bar) The giant imaginary bottle of whiskey is with me.
Rocko: What are you?
Bobby Whiskey: I'm Bobby Whiskey Rocko, and if you hang with me, you'll become funnier, smarter, and more handsomer, not that you need it. Damn, you're awesome.
Rocko: Well, that's the nicest thing a beer induced hallucination has said to me, let us be chums.
Bobby Whiskey: Ahhh yeah.
Rocko: Ugh. You drink this crap? What is it?
Rocko: Wah tur?
Gimpy: (giving Nitz a fake I.D.) Remember, young Padawan. With great power, comes great responsibility. Heh-heh, Spider-Man.
Rocko: Ugh! Bobby?
Prisoner: Shaddup! I'm-a-gonna make you MY bitch! (sniffs Rocko's adult diaper) Ewwwww! Stinky!
Rocko's fake I.D is just a card that says "I am 21 so drinking is YES" next to a apicture of him.
Apparently, Jack Hammer Awareness Day is not a real holiday.
Rocko gets out of jail on "Jack-Hammer awareness day" It's seen on a banner behind Rocko.
Nitz: I learned it from you.
This line was taken from a famous drug PSA, where a father finds a box of drugs in his son's room and when asked who taught him to do the drugs, the son looks at his dad and says the line.
Gimpy: With great power, comes great responsibility. Heh-heh, Spider-Man.
This is the lesson that Marvel Comics hero Spider-Man learned the hard way when he let a burglar run past him and didn't do anything, who would later murder his Uncle Ben.
