The Steel Magnolias costars appeared on Jimmy Kimmel Live last night, where the host set up a hilarious game show for the two. The premise, according to Kimmel, was to find out which actress has the foulest mouth. Roberts and Field had five seconds each to come up with a different curse word, no repeats. The result? Well, you just have to see this one to believe it. Check out the video below to see what we mean. Hint: Sally Field is a total badass.
