Actor Mo Brings Plenty may be a quieter personality on the set of Yellowstone, Marshals, and other projects, but he delivered the excitement to the NASCAR fans in attendance at Kansas Speedway.

The veteran actor gave one of the best commands while telling the drivers to start their engines. He created a memorable moment while setting up Saturday night's O'Reilly Auto Parts Series race.
The command started with Mo Brings Plenty thanking the Kansas Lottery and the racing fans in the state. He then yelled, "Drivers, start your engines" with his fist in the air. He held the last note for a very long time as the drivers fired up their stock cars.

This is not the first time that Mo Brings Plenty has shown up at NASCAR for a special event. The Yellowstone actor also attended a race at Texas Motor Speedway in April 2025. He served as the co-Honorary Race Official for the Cup Series race.
The O'Reilly Auto Parts Series does not usually have the biggest names serving as the grand marshal. Sure, Arizona Cardinals defender Budda Baker held this role prior to a race at Phoenix Raceway, but the secondary series traditionally brings in sponsor-related figures to give the command to fire engines.
The Cup Series races are the ones featuring the big names most weeks. These races have such celebrities as Morgan Freeman, Chris Evans, Patrick Warburton, Nate Bargatze, Glen Powell, Bill Murray, and Shea Whigham among many others.
Some of these personalities try to bring the noise to their commands. Others go the quieter route. Freeman, for example, did not have much energy when he gave the command at Las Vegas Motor Speedway in 2025.
Evans went the opposite route when he gave the command at the 2014 Daytona 500. He brought the noise when he told the drivers to start their engines.
Of course, the most memorable person to deliver the command is actor Kevin James, who has been grand marshal multiple times. His command before the 2007 Pepsi 400 at Daytona International Speedway has become legendary to sports fans.
