I always thought that Jotaro's one-liners were always corny and bad, but that was a core part of his character. Like he always wants to sound cool but he's actually awkward and fucks it up.
I did love the bit where Jotaro just goes "Avdol, say something" and Avdol reuses his line from the previous episode.
Also, "Captain Dragon"'s real name is Captain Tennille (Avdol refers to him as "Tennille-senchou" so thats an easy one to miss)
