The ad they showed just before the video: a guy's trying to get a date with the gal behind the bar at a beach, when this Watcher in the Water shows up out in the ocean and begins attacking someone! (The guy then splashes in to rescue him, using a beach umbrella end as a sword, and as he comes ashore says something about taking the rescued man to the hospital, and asks if she's still on for a date tonight, and she of course says "yes". Turns out the beast and the rescued man were two friends of his, going through the charade for him.)
I kept expecting an Elf and two strangely-dressed Men to join in the rescue...[laugh]!
