De-referencing short urls is a pain.

http://www.longurlplease.com/ is quite nice.

Bookmarklet, FF extension, and a JSON API. I've used the API, and it was a pleasant experience.

I wrote a Chrome extension that uses their API, but beware that their API does go down from time to time.

The bookmarklet works great. Thanks for the reference.
