Stays crunchy, even in seawater

So, the current episode makes fun of underwater life in comics. Comic book scenes in Atlantis and other undersea cities show people drinking from goblets, using electronics, and wearing long gowns. Both Aquaman and the Sub-Mariner sleep in beds that look like they were bought from Macys.

I love mermaids, but I think that the everyday life of an underwater human would be very different than ours. Tom Hanks' character chose to live that life at the end of the movie Splash (for love), but I wonder how he adapted those first few days.
