Well, there's a new movie version of The Lone Ranger coming out soon, and seeing as how the Lone Ranger has a trusted horse named "Silver", why not use this propitious occurrence as an opportunity to tie an ad campaign about investing in silver (the precious metal) into the movie?
So the spot would open with the Lone Ranger escaping some dangerous situation and defeating some bad guys while riding his trusty heroic horse Silver, after which the Lone Ranger rides up to the camera and says: "Hi, I'm the Lone Ranger. There's just nothing I trust more to get me through tough, uncertain times than Silver here (patting his horse on the neck). And just like I can depend on Silver to keep me safe, so can you depend upon silver to help you weather turbulent and threatening financial times. Silver is completely dependable and trustworthy. It has great value, a value that lasts and stands the test of time, while greatly increasing your investment. So if you want to secure your future, put your trust in silver; I know I do!" (While he is speaking, he pulls a small leather satchel out from around his waist, and he opens it, and pours silver coins into his hand, after which the shot cuts to a still frame of stacks of silver coins in front of a safe with the logo and name of the company the commercial is for, and then to a chart of the rising value of silver over time in recent years.)
Then the Lone Ranger spurs his horse, exclaiming: "High goes Silver, hooray!", and he rides away, off into the sunset. (Or maybe: "Buy more Silver, today!", and he rides off into the sunset.)
