Okage got me with one of the funniest encounters I've seen in an RPG. Ran into the "Bad Poetry Golem" which is the final dungeon's version of a Metal Slime from Dragon Quest. See: Hard to hit, will run if prompted, but gives insane EXP/Gold. The twist is, that golem stole 100,000 Gold and ran.

I am now deadass broke in the final dungeon and laughing my head off the game had the balls to do that.
