(Arlington, TX) — A Dallas police officer leads a sort of double life as a Dallas Cowboys superfan.

Jaime Castro has been on the Dallas police force for more than 20 years.  But on game days during football season, he puts on a costume based on a Cowboys uniform and transforms into “Ballz Mahoney,” one of the most popular characters at Dallas home games.

This Saturday’s NFC Wild Card playoff game against the visiting Seattle Seahawks will be Castro’s 175th home game in a row.
