Los Angeles is reacting to another earthquake which hit the region today.
The 'quake, which measured in at 4.4 on the Richter scale, is not believed to have caused any major damage and no injuries have been reported.
But NFL veteran-turned broadcaster Terrell Davis wasn't to know that at the time.
As the video above shows, the former Denver Broncos running back was hanging out on the set of NFL Network when the tremors set in.
And his reaction is priceless.
A look of pure shock and repeating the word "earthquake" is not quite what they teach you in school, but in fairness it is not a situation we have ever found ourselves in and would no doubt react in a similar state of confusion if we ever were.
Davis tried to brush of his scared demeanour later in the show, but unfortunately for him the cameras were rolling - reportedly just a few miles away from the earthquake's epicenter!
