the noted isnt really meant as a gag, i think it's to demonstrate his youth and unfamiliarit with the whole heroics business. Robin was as young but had been doing it for 4 years under Batman. Beastboy has a lot to learn still and the closest thing he has to a mentor is his older sister, not exactly the hard disciplinary who can teach him everything about being a hero is she.
