Clicking on your own Adsense

Ooops, I just clicked on my own Adsense, which is against the agreement. What do I do if I am really actually interested in the ad that is on my site? For instance, the one I clicked was for Widgetbox, a directory of web widgets for blogs. Now, I am always looking for stuff to add to my sidebar. What do I do in such a situation???? So, Blogger people, please tell me. In the meanwhile, I will be looking at some neat widgets
