A Barcelona comedy club brings rationality to humor. How funny.
Seventeen laughs, eight giggles, four guffaws and one snort till the
snot slipped into your cerveza? That'll be 6.6 euros, please.

This, I imagine, was the sweet sound of the checkout at one Barcelona
comedy club, after it took the bold step of charging its customers not
for the fun, but for every single sign of humor.
The Teatreneu Club thought it might be an amusing experiment -- a sort of world first -- to give willing customers an
iPad
equipped with facial recognition technology that captures every laugh.
The iPads are attached to the seat in front and keep score of the laugh
total.
