WP Custom Taglines adds a meta box to your posts and pages with two options, Enable Custom Tagline, and Custom Tagline Content. Checking 
“Enable Custom Tagline” will cause your site to display the contents of the “Custom Tagline Contents” field on your site when that post or 
page is viewed, instead of the sitewide tagline.

Custom Taglines

WP Custom Taglines allows you to specify a custom tagline for each post or page that will override the sitewide tagline for that post or page.

The Pearl Jam Taglines plugin allows you to randomize your self-hosted WordPress blog’s tagline with one of 50 classic Pearl Jam lyrics. Because let’s face it, Eddie Vedder is much better at writing clever things than you are.
The tagline will be updated on each page load (in the next version, you’ll be able to customize this)
Please submit any bug reports, support questions, or requests <a href="http://anthonybubel.com/contact/" rel="nofollow ugc">here</a>. Suggestions/requests for the addition of any of your personal favorite lyrics are always welcome! Please note that requests are not guaranteed to be added.
