I Need a "Favorite Icon"

Everyone seems to have nifty little icons for their websites that show up in the address bar and on their bookmarks. I need one for my site, but I can’t think of anything. Does anyone have any suggestions? (And no, I won’t even consider a horse’s ass…) An elephant at a computer keyboard, perhaps? Probably too detailed for that small amount of real estate. Email me if you have a suggestion.
