How to add floating side bar?

[DISLEX]

I want a floating side bar on the side of my forum.

Just like this site: http://www.cracked.com/article_18750_17-images-you-wont-believe-arent-photoshopped-part-6.html

How can I do this? Talk to me like I am dumb!

Thanks!

Great question.

What happened to this place? I NEVER get help anymore. I have a ton of question threads and no answers.
