This is a Ten Commandments joke right? Did the Vikings sail into the Mediteranean Sea? They made it to America so it’s possible. Although that was in what the 1000s or 1100s? Still an era away from Moses. Perhaps Hagar is actually some sort of proto Viking. The one all others are descended from.
Also it’s a bit of a slap to Odin’s face. When was the last time Asgard was mentioned in a Hagar the Horrible panel? Now THATS a comic!
