If you haven't been living under a rock since the creation of the internet, then you've probably seen the viral video 'David After Dentist' from years back, where a kid is out of it after getting a procedure done at the dentist. His parent's asked him questions and videotaped his hilariously loopy and strangely philosophical reactions.
This seemed to inspire a whole bunch of other ruthless people videotaping their family members after their dentist procedures, but this one might take the cake. Why? Because of the preparation. They pre-recorded an emergency broadcast alert, for god's sake. Watch the video below and be thankful these aren't your family members.
