"Best $2k I Ever Spent!" David Guetta, The First Musician Immortalized At Grauman's Chinese Theatre

And although the Guetta thing seems particularly grating because you'd think the first musician to ever be immortalized at Grauman's might be, y'know, an actual musician, it's not like there aren't a few other duds that have been encased in cement over the years. While Adam Sandler is certainly world famous, movies like Jack & Jill must make you wonder if someone's ongoing career has ever made them take a plaque away before. And then there's Robert Pattinson, Taylor Lautner and Kristen Stewart. I can't even imagine how future generations, far divorced from the modern culture wars that even made Twilight possible, will view those movies, but if there is a God, they will turn out to be as much of a mockable curiosity as, say, Zardosz.
