I posted a Barbarian build like that before. Rage, Frenzy, drunk (battle wine), Blood Frenzy, Rage (the spell), Marruspawn Rage and so on.
The coolest barb build I've done was the ubercharger with Sadism (10dmg=+1 stacking to skills) and one Rank in the Knowledge Skills. The comment sold it as something like the world's most intelligent researcher, who developed new theorems in DNA science, was really just a pissed off illiterate savage. Good times.
