Outdrinking a Norse? That's a scary concept. But if anyone could do it, it'd be another deity-like thing person. Don't get alcohol poisoning! Can you even get alcohol poisoning? I've always wondered about that. I know that some of the Christian doohickeys can't, but things might be different, from pantheon to pantheon.
Now I'm feeling all scientific about the alcohol consumption of Gods. Thanks, Mel. :P
