Hiring an impersonator to mimic a famous person for the intro to your podcast could potentially infringe on intellectual property rights, particularly if the impersonation is too close to the original and could confuse listeners into thinking they are hearing the actual famous person. This could lead to legal issues related to identity rights, trademarks, or copyrights depending on the jurisdiction and the laws governing impersonation and intellectual property.

If you are considering such an approach, it's advisable to consult with a legal expert who specializes in entertainment law or intellectual property to ensure that your use of an impersonator is within legal bounds and doesn't infringe on any rights associated with the famous person you are trying to mimic.
