You may have killed a few minutes playing it at work on Friday. 

And you're not the only one . . .
RescueTime is a monitoring app for businesses that tracks which software and websites their employees use at work. 
According to their calculations, the average Google user spent 36 seconds more time on the site Friday than they normally would.
Google users spent a total of 4.82 MILLION hours playing "Pac-Man" on the site.

Overall, Google's tribute to "Pac-Man" cost companies more than $120 MILLION in lost productivity from employees playing the game at work.

$120 MILLION in lost productivity is enough to pay the salaries of Google's 19,835 employees for six weeks.
