Actor Jonah Hill went on "The Tonight Show" with Jimmy Fallon on Tuesday to practice giving the command in advance of Sunday's NASCAR Sprint Cup Series race at Pocono Raceway, where Hill and fellow movie star Channing Tatum will serve as Grand Marshals.
Turns out, he could use a little more work. A self-proclaimed slow and cautious driver, Hill said he might not be the most qualified to utter the most famous words in motorsports.
In fact, the actor said rather than the usual "Start your engines!," he may say, "Drive at a respectful pace" or "Don't text and drive." (Are you reading, Brad Keselowski?)
Watch the clip below to see Hill practice giving the command just days in advance of the Pocono 400.
