Amanda Conner and Jimmy Palmiotti understand the defining element of Hal Jordan's character.

Sure, the writers of Harley Quinn's Little Black Book may have played rather fast and loose with the "rules" of the variously-colored power rings in the second issue of their bi-monthly team-up series (drawn this time by John Timms and Mauricet), just as they ignored the timeline of the New 52 in their first issue (I guess we can chalk the title's continuity-lite status up to it having an unreliable–meaning "insane"–narrator), but in the above panel they demonstrate that they know exactly what it is that makes Hal Jordan who he is.

Hal Jordan is a guy who gets hit in the head a lot.

There are also a few gags about Harley touching Jordan's butt (which at least one of you will likely appreciate), and the more standard line of making fun of the character: His complete lack of imagination when it comes to power ring constructs, the defaults being a handful of the types of sports equipment that might have been found in your father or grandfather's childhood toy box.
