Halo day

Calling in sick to work on the release day of a highly anticipated video game so time can be spent playing the new game. Named for the large number of people that called in sick on the day that Halo 3 was released.
Battlefield 3 is coming out next Monday; Fuck work I'm calling in a Halo day.
