These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
That's actually the Flaming Lips performing, with Tom Jones doing the vocals.
Not to mention the episode "In Space, No One Can Hear You Rock", guest-starring freaking Megadeth. Not only that, they gave Dave a laser guitar. Dodgers practically speaks for the viewers throughout the final few minutes.
Designated Villain: Melvin. The episode where he appeared suggested people should hate him for opening a rival restaurant next to I.M. Neighborly's and take Neighborly's customers away by offering them free sodas and also suggested it was okay for Dodgers and Neighborly for sabotaging Melvin's in a way that, in real life, would get them arrested for not only damaging private property but also endangering the lives of everyone inside.
Dodgers and the Martian Commander. The episode "Enemy Yours" goes out of its way to make them act like disgruntled lovers, what with Dodgers panicking when he finds out that Marvin has other archenemies and Marvin making excuses to his current archenemy as if Dodgers is some Psycho Ex-Girlfriend who is trying to sabotage their current relationship.
Canon example: Dodgers and the Martian Queen. Seriously, the woman veers between wanting to destroy him and wanting to marry him. However, it seems a bit one-sided, as when confronted with the Queen's feelings, Dodgers usually either exploits them to his own advantage, or outright rebuffs them. If he manages to remember that they were ever engaged in the first place. When they really did get married, he had no problem with it, until Marvin tricked him into leaving her. When Dodgers found out he was duped, he seemed pretty mad. Even after I.Q. High reveals to her that Dodgers is an idiot she still finds herself strangely attracted to him.
Genius Bonus: When there's a throwaway joke about Busby Berkeley, you know you're in for a lot of these.
To say nothing of Sinestro going up against a purple-skinned character voiced by a Tara Strong.
In "The Green Loontern," Dodgers' "Oath" (which he makes up on the spot) starts out with "In blackest day and brightest night," which seems to be just a humorous reversal of the normal script. A few years later, this is how the Sinestro Corps' oath starts.
In one episode, Dodgers comments on EYSC's upcoming engagement that wives start out "sweet and innocent", and then "You wake up in an empty house handcuffed to a radiator." A few years later, this is exactly what happens to the Eleventh Doctor on his first outing.
