I like this video because most similar videos are set to music or a commentary that has been pre-recorded.
This is the actual real-time expressions of the marine biologists exploring the deep sea. And they sound like very polite, but happy scientists.
I think my expressions would be peppered with a bit more coarse language, as in “WTF IS THAT?! ARE WE SAFE?!” But I think the one expression that would get me kicked out of the room would be my best Scotty impression from Star Trek IV: The Voyage Home, as I yelled, “Admiral! There be whales here!”, over and over again.
