Justified star Timothy Olyphant has revealed he used to mess with co-star Walton Goggins over one of his character's traits. The two acted opposite one another in Graham Yost's neo-Western series, which ran six seasons on FX, between 2010 and 2015. Based on "Fire in the Hole" by Elmore Leonard, the show spawned a successful spinoff, Justified: City Primeval.
