Is this just too weird? Or am I just so out of it that I can't imagine how jewelry in the mouth is supposed to be attractive?

From " Grill lets you put your money where your mouth is:"

Paul Wall has mastered the art of conspicuous consumption, and his favored medium is his mouth. Thus, if the Houston rapper has pearly whites, we wouldn't know: Wall never appears in public without wearing a grill -- a removable cosmetic mouthpiece made of gold or platinum with diamond inlays.

Wall is flashing one such designer dental piece, also known as a front, on the cover of his 2005 album, "The Peoples Champ," which is loaded with references to bejeweled bicuspids ("Say cheese and show my fronts/ It's more carats than Bugs Bunny's lunch").

His jewelry box of a mouth is also open for public viewing in the video for Nelly's smash hit "Grillz," an ode to oral ostentation.
