Christina Applegate on When Her Potty Mouth Wasn't So Funny

https://youtu.be/OWceLKNcLpY

Christina Applegate gets the laughs rolling when she spews out raunchy words in comedies, but when she was a youngster, her foul mouth got a much different reaction.

"I was in nursery school, and my mom got called in because I was running around, yelling [bleep] all over the place. Preschool, preschool - five," the 43-year-old recalls to host James Corden Thursday on "The Late Late Show."

Who does she blame it on? "This kid Nathaniel," she says. "His dad was a drummer. Yay, 1970s!"

But her childhood faux-pas is far more tame compared to her family trip gone terribly wrong in "Vacation," opposite Ed Helms, in theaters now. Watch the trailer below.
