What out-of-the-way secrets have you found?

We all know that the cardinal rule of exploration in any video game is to check under every waterfall for a secret passage. That's a given. But true exploration shouldn't stop with a wet dip and a slow-motion hair flip as we emerge sparkling into the sun. Developers have been hiding funny or interesting little secrets in out-of-the-way spots for years -- and MMOs are a prime example of this.

I recently read a piece on Warhammer Online that reminded me how the developers used to watch beta testers do all sorts of acrobatics to get to hard-to-reach locations in the game. Instead of stopping them from doing so, the devs put special bosses or other secrets in these locations to reward exploration.

I'm sure you've discovered many secrets when you've gone off the beaten path in MMOs. I, for one, would love to hear about them. Share, please?
