Visitor Smashed Priceless Clock!!

Last week, a visitor to the National Clock and Watch Museum in Columbia, Pa., got a little problem with a museum clock. 

In footage caught on surveillance camera, you can see the man fiddling with a one-of-a-kind hanging wooden wall clock while his companion looks on. 

Unfortunately, the clock comes smashing down, breaking into pieces. The museum decided to share the video on its YouTube and Instagram accounts as a warning, and as a reminder.

He wishes he could turn back the time..
