Nathan Fillion Surprises as Guy Gardner

The image is a side-by-side comparison: on the left, a comic book panel of Green Lantern (John Stewart) with a speech bubble saying 'WANNA MAKE SOMETHIN' OF IT?'. On the right, a blurry, green-tinted photo of actor John Stewart (from 'The X-Files') pointing his finger forward with a green energy beam emanating from it. The juxtaposition creates a humorous visual pun.
