Doesn't matter. Waits v Frito Lay
That's an impersonation of a parody song in his style. This is a voice actor who has a voice that's kinda similar to ScarJo and kinda similar to Rashida Jones but not quite either one doing something different. Cases are not a spell you can cast to win arguments, especially when the facts are substantially different.
