They're extremely fun to read sometimes bordering of fantasy and fiction. I don't think I've seen one mentioning the undead crawling their way to the surface from their earthen tombs but I probably just haven't read enough

Rest assured if I ever go public I'll insist on putting a few in there. A battalion of armored octopi marching ashore with undefeatable sea ordnances enslaving humanity by tentacle could prevent us from hitting our quarterly numbers...

I've put so many hidden jokes like that in terms of service and privacy policies over the years.
