Oh my. I'm laughing so hard I'm gasping for breath.

This was one of those rare beasties: A sequel that was actually far better than the original. And given how good the first story was, that is really saying something.
I love how you turned the "How mad are you" line from the show on its head. And you do make a compelling case about why Clark might be mad at Lois.
I've never been hungover from alcohol, but twice in my life I have been dehydrated to the point of experiencing what I imagine a hangover would feel like. You've captured that wretched feeling well, while still imbuing the story with a lightness and humour. And the "Drunken Sailor" filk was just icing on the cake.
Brava!
Joy,
