This, the work of @BizzaroZaun, is one of the best Mike Francesa impersonations you will ever see. And it's not just Francesa's voice that Zaun nails; everything about this impression—the smugness, the dismissive attitude towards callers, the fact that Francesa would have been a loyalist stooge in 1776—is pitch-perfect. Now go ahead and watch this five or six times.
