Well, Luke, let me put it this way: What major life-changing investment have you made, simply because a famous person did the same thing?
If you were talking about a celebrity *endorsement,* with some character like William Shatner doing a half-hour infomercial, I *might* expect a few results. But just having a famous person in a Dewar would probably elicit a shrug-response such as, "Famous people do that kind of thing."
