Mike Sexton and Mike Matusow were just involved in a small pot that ended before the flop. However, as not to confuse the audience, TD Robbie Thompson referred to Matusow as "Mike" and Sexton as "Mr. Sexton."
"How about 'the idiot limps in' or 'the nit folds?'" Matusow said, referring to himself. "Or maybe 'the ambassador raises?'" he said, gesturing to Sexton.
They settled on calling Matusow by his entirely appropriate nickname-- "The Mouth."
