Not in RQ, but in Stormbringer (also BRP), they had the rule that you could trade in any of your stats for more POW on a 2-for-1 basis. So our pal Tom rolled up a sorceror, put his best roll into his INT (he got a 20, not out of hand for Stormbringer), and sold every other stat down to 1 -- STR, CHA, SIZ, everything -- for a POW of 37. He lived in our big bruiser's backpack and stuck his head out to cast nasty spells occasionally. Probably he should have died on a couple of occasions, but he was too cool a character, and Tom was never an abusive gamer.
The weirdest I got in RQ was a duck who was sold into the Lunar Empire as a gladiator, promptly won his freedom, and threw in his lot with the Lunars, ending up as a Rune Lord of Yanafal of the Seven Mothers and going on his first heroquest just as our GM moved out of state, after ten real-time years of weekly/bi-weekly play. Good times...
