What's mine is mine and mine and mine.
And mine and mine and mine!
EDIT 05/02/2015: New version with the Real Oath!
Ladies and Gentleman, with this last pic, this project about the Seven Corps in the Green Lantern Universe is finished.
Let me introduce you to Larfleeze, Agent Orange, the creature that want all the thing in the universe and that control the Orange Light of the Avarice.
Original pic is from Blackest Night #0
PS: I've done a pic with all the seven "silhouettes" , a good wallpaper like i've done with the Famiglia Vongola... if you want to see it, tell it in the comment, ok?
Be it in bright of day, or black of night.
I lay claim to all that falls within my sight,
To take what I want, that is my right!”
but its all very good work, ever thought of doing the Black and White Lantern Corps I could see Nekron being the black Lantern, but i think the only white lantern left is dead man
and anyway, i was thinking about black and white, but they are not really a corps... the black lantern now is only formed by black hand, the white corps is rpobably something occasional so... maybe, if in this last saga of GL they'll reappear like real corps, i'll do something u_u
Johns confirmed, at San Diego Comic Con 2009, that the oath required to recharge Larfleeze's ring has not been heard despite rumors of it being the word "mine" (a demand regularly made by both Agent Orange and his Orange Lanterns). Regardless, in an interview with Newsarama, he also stated that the Orange Lantern oath was his favorite. 
Given that Larfleeze is the only ring wielder not to recite his oath in Blackest Night #5 (Hal Jordan instead constructed a giant hand to shove his face directly into his lantern, resulting in a 100,000% power ring charge), a fan asked Johns about his plans for the character at WonderCon 2010. Remaining vague, Johns responded that Larfleeze's oath would be revealed "soon." Lex Luthor has recently stated that he "swore an oath to serve the Orange Lantern Corps (and what an interesting oath it was)".
On youtube you can find some unofficial oath that some fans created using the same metrics of the others oath, there are even some alternative forms of the oters oath... anyway, it was really good!
This Clear things up?....
In the epilogue of "The Wrath of the First Lantern" story arc in Green Lantern #20 Larfleeze revealed his oath and his ring charged to 100% and it is as follows:
“What's mine is mine
and mine and mine,
And mine, and mine, and mine!

Larfleeze really is the strongest of the lanterns. Also, he's the most unstable of them, making him an even bigger threat
