While it may not improve your search engine rankings any there are ways to have fun with the search engine results page. If you place escape character codes in your title you can make it show up with arrows or stars on the search engine results page.

for a star use & # 9 7 3 3 with no spaces between the characters.
for an arrow use & # 9 6 5 8 with no spaces between the characters.

I actually learned this a few weeks back while reading Search Engine Yearbook 2004. You can actually use this trick with many other symbols too. Here is a post from Webmaster World about it.
