If you could have any person who you have ever heard be the voice directing you through your GPS navagation device, who would it be and why?

Anybody who you have ever heard speak; famous people, loved ones, fictional characters(only from media with audio), etc… Who would you pick? Remember, it has to be somebody that you have heard. You can’t pick somebody like Napoleon just to find out what he sounded like
If you don’t have a GPS system, just imagine that you do.
Prompted by the fact that Snoop Dogg recently made a recording for TomTom GPS systems.
