Ricky Bobby is a cocky, immature, and lowbrow NASCAR driver who is obsessed with winning and lives by the motto "If you ain't first, you're last". He is known for his ridiculous lines and antics, such as "I prefer the baby Jesus to the adult one" and "Well as the late Colonel Sanders said... I'm too drunk to taste this chicken". Ricky's life takes a turn when he faces competition from the French driver Jean Girard, leading to his downfall and eventual quest to regain his former glory. His character is a mix of patriotism and foolishness, with a tunnel vision for his career that often leads to comedic situations.

Cal Naughton Jr. is a fictional character portrayed by John C. Reilly in the 2006 comedy film Talladega Nights: The Ballad of Ricky Bobby. He is the loyal best friend and teammate of Ricky Bobby, with whom he shares a close bond and a signature "Shake and Bake" racing strategy. Driving the No. 47 Old Spice-sponsored Chevrolet for Dennit Racing, Cal is known for his quirky personality, unwavering loyalty, and humorous musings about Jesus and life.
