Game Master: Bobcat's Dungeon Master Role in Episode 7 when the Puppet King attempts to use Starfire and Raven as slaves. Raven wants to make her and Starfire immune to the attack along with making Cyborg snapping out of the attack as well.
Beast Boy: Dude, she ruined breakfast! She should be the one apologizing!
Robin: I agree with you, but women are irrational creatures. It's why they always win arguments.
Starfire: I...am...not...IRRATIONAL! (bursts into tears)
Robin: (to Beast Boy) Look what you made me do. Now go apologize to Raven while I deal with Starfire crying for the next 3 hours.
Lampshaded the Obscure Reference: In episode 11, after a few references were made, Robin wondered who declared it obscure reference day. He then gets annoyed when Starfire claims a Doctor Who reference would be obscure.
Schedule Slip: Episode Seven comes eight months after Six, with an Apology Vid about in the middle of the break. And then, Episode 8 came out a year after episode 7. Episode 9 finally came out, almost a year later. Episode 10 came out 2 months later. 9 months later was Episode 11 and 9 months after that finally came Episode 12 (which lampshaded how long it took to get there), which ended the season (they skipped Mad Mod).
Self-Deprecation: Robin describes Slade as "almost as bad as the guys who make an abridged series of an 8-year-old cartoon show".
Or when Raven and Beast Boy break up after "dating for ten seconds".
Beast Boy: You're a hot girl who runs around in a swimsuit. Of course I like you.
Shout-Out: Raven's 'destruction' quote above is a reference to a Futurama quote about 'murder.'
There have been a couple references to Freakazoid, too; Raven "throws a barrel" at a monster in episode three, and the dance club in episode two plays the Freakazoid theme song. Also, Beast Boy uses the phrase Crud Vapors as an expletive.
Sure, Let's Go with That: Aqualad confesses to having no idea what Trident wants with nuclear waste. Robin suggests that maybe Trident thinks he's on Captain Planet and just pollutes as a hobby. Aqualad responds with this trope. (Unlike most examples, it's actually used in agreement)
Suspiciously Specific Denial: Starfire thinks of Robin in terms of "friendship and nothing else, and certainly nothing involving chains and hot wax."
