Actors Jenna Fischer and Angela Kinsey, who co-starred on the hit NBC comedy series and have released a book about the show, wrote about how a stunt driver “swerved hard” and made the cast go “flying” inside of a bus, Mashable reported.

The episode, “Work Bus,” featured guest director Bryan Cranston, who is known for playing Walter White in the series “Breaking Bad.” In the book, The Office BFFs: Tales of The Office from Two Best Friends Who Were There, Kinsey joked about the irony of Cranston’s ties to the episode.

A scene featuring Schrute’s bad driving caused the show to hire a stunt driver to fill in for Wilson, Fischer explained.

That’s when the show’s assistant director told the stunt driver to swerve, Kinsey wrote.

“What no one had considered when they told this stunt driver to swerve as hard as he could without flipping the bus over was that none of our office furniture, props or set decorations were securely tied down.”.
