How do I get more people to click on my ads?

Hi
Are there any methods which will perswade users to click ads on my site?
If you visit, my site, http://www.thefunstuff.org, you will see an ad on the side bar, under the featured games bit and down at the bottom
Even though my site is still realatively new, no one clicks on them
