Question re: Mail program

I use the Mac Mail program and have hundreds of signatures that I've set to use randomly for each e-mail I send. People have commented that they like these signatures and I'd like to collect them all in one word processing document to send out. I know that the signatures are stored at the User level in Library under Mail. The problem is that they're in webarchive format and I can't just dump them into a word processor document. When I put them in a web page, a new page opens for each quotation so that's no use. Any suggestions? Thanks
