The highlight to every teenage boys sports illustrated subscription every year.

With the amount of beautiful women wearing nothing on television and the internet, the Sports Illustrated swimsuit issue does not have the same impact it did back in the day. Does not mean I still don't give it a glance every year when it comes out. Whenever it comes out, the first thing we all see is the cover.

Sports Illustrated just celebrated fifty years of the swimsuit issue and to mark the occasion they counted down the top five covers of all time. I thought Kate Upton should have been number one, but maybe I am just biased. Here's to hopefully another fifty years of the swimsuit issue of Sports Illustrated.
