Enjoy This Dam Status Message

Welcome everyone. I am your dam guide, Arnie. Now I'm about to take you through a fully functional power plant, so please noone wander off the dam tour. And please, take all the dam pictures you want. Now are there any dam questions?

Explanation: The Griswolds tour Hoover Dam. I love this joke. Every time I drive past a dam on the highway, I exclaim, "Dam!" Always good for a laugh (from me, at least).
