The whole "Ruby Tuesday blows itself up" thing went down earlier this week.
In summary: The restaurant didn't explode. In the video, a similar-looking restaurant next door blew up instead. The crowd looked understandably aghast. I mean, a casual-dining restaurant that didn't know it was going to be blown up is probably going to have people in it.
As I'm sure you've guessed, it wasn't a real accident. (That news is good, if unsurprising). It wasn't even a real restaurant. It was just a model blown up in a studio. There's behind-the-scenes footage at Ruby Tuesday if you are still interested.
