So I have discovered a new thing...well, actually I discovered it through my daughter...The Mole on Netflix...just finished binge watching every episode and I am going to pay for it tomorrow, no, actually today as it is 2:21 a.m....sheesh!!! Wow - this reality teevee crap really does suck a person into it!
But, on the original topic, I agree with you - it would be fun to experience a flash mob.
