Lipsumlet - The Lorem Ipsum Bookmarklet:

This is something I created today. I was using other lipsum sites and realized I'm doing something in multiple steps (go to site, highlight block of text, hit command + c, close window) that should really only have to take one (click link). So I've created a lipsum bookmarklet. You just drag it to your bookmarks bar and click it anytime you need a paragraph of lipsum. The bookmarklet opens, automatically copies a paragraph of lipsum to your clipboard, and closes in 3 seconds.

I just put this up seconds ago, so if anyone catches any bugs or would like more bookmarklets added to the site(short paragraph, longer paragraph, lists, etc...), feel free to get in touch. By the way, here's the bookmarklet link if you don't want to visit the site: lipsum bookmarklet.
