Nobody mentioned the James quote? "It's times like these that make we want to go straight" That's hilarious.
People are also dumb and assume that.
Once inside the city, while Ash is uncertain as to why Misty left, Brock is repeatedly dropping subtle hints that he knows she's a gym leader in Cerulean and can even see into why Misty doesn't want to come back. This is evident by the scene where Ash asks Brock for advice about the gym leader, Brock mentions that he knows the leader's "special move," but won't tell out of respect. A respect that he has yet to show to any other gym leader that Ash has gone up against. The clincher to this is those golden lines that no one seems to understand. Just before Ash goes to the gym, where Brock knows he'll see Misty, he says:
Brock: "Well... I have some stuff I need to go check out."
Ash: "What stuff?"
Brock: "Just... stuff. See ya later."
Anyone that's hit puberty should have known exactly what Brock was doing. I'll put this from a guy's POV. Guy A and Guy B are hanging out somewhere. Suddenly, Guy B sees Girl 1 walking over to them. Knowing that A and 1 have an unsatisfied romantic interest in each other, what does he do? He says, "Hey, 1, listen. I've got [wink]something I need to do.[/wink] So, I'll see you later."
The fight has them bickering like a couple and TR's vacuum tube that sucks up the water was so full of phallic imagery, it's a wonder how it was aired at all.
Once the fight is over, Brock reappears and asks Ash, "Hey, man, how'd it go?" Which is obvious guy code for: "Did you get any?" Ash replies with flashing the cascade badge and the show ends with him and Misty arguing over if he really deserved it at all.
