Grand Marnier is a bit late to the "user-generated contest" party, but at least they're fashionably late. Create their next ad and you could win a trip to Paris and other gimme, gimme, gimme prizes. But wait! This is really a contest for copywriters because you change the art direction or layout of their current ad.
See the picture inside the Grand Marnier bottle? Yeah, that's all you can change. The contest should really be called "Tweak Our Next Ad. Visit mygrandmarnier.com to enter.
