I'm suprised no one mentioned Gragas.
Afterall, he said it himself.
"The worth of a man can be measured in the length of his beard, and the girth of his belt buckle."
Gragas is an object of veneration according to Olaf! They'd make fine drinking buddies!
1. Both have awesome beards.
2. Both like to drink alcohol.
3. I'd assume both get into some of epic brawls, with one being called "The Rabble Rouser" and the other called "The Berserker" and all. <_<
