On another game, I set myself on fire as a magic user character because I as a player did not read the description of the spell I was using, resulting in my death.
Before you say, "Oh but the GM should have let you redo it because you as the player didn't know the effect of the spell!", I will add that we decided to run with the character's death because I was RPing him as incredibly absent minded to begin with, and it would only make sense that he would forget how his own spells work and take himself out of the picture that way. In fact, we joked up to that point that any other death would be unworthy of his legendary airheadedness.
