Today is a great day for Sports Illustrated subscribers and readers. The mag’s annual Swimsuit Issue hits news stands. Be on the lookout for employees and co-workers taking longer than normal bathroom breaks. In a surprise move the editors put R&B singer Beyonce on the cover of the magazine….without a doubt to hopefully sell more copies. Click here to see Beyonce’s cover.

Another cool office contest (almost as cool as NCAA March Madness office pools) is to take bets on how long the issue will last at the office before someone pockets it and takes it home. For even more fun make additional bets on who it will be that cracks and walks out with the buxom issue.
