How do you make a a word also a link to a website?

[La Promenade Morte]

I'm trying to put one of those "ThisCrush" things in my signature where people can comment about you. It's kinda like the "Truthbox" on Facebook. I want to put the word "Crush?" in my signature so people can click on it and it will lead them to this website:
http://www.thiscrush.com/~xmuffinsxbleedxfrostingx
Anyways, can anyone help me?
