In my head canon, vanity is a key component that ties Hal & Ollie together among the Justice League. Outside Batman, they normally have the best poses during group shots. They are so disparate, yet deep down, both think they the sh!t.
I also think vanity is the link between Hal & Sinestro. One thinks he can breakdown/change the other, due to some mutual quirk. It was very amusing when Ollie complimented Sinestro's facial hair during Rebirth 2005. Game recognizes game, as the saying goes.
I think Guy also picks up on Hal's vanity, and tries to duplicate it to unfortunate results.
