Oh, do I have a story for you. 2nd edition AD&D, my wife, who was playing a ranger with a bugbear hatred, was attacking a bugbear compound. She had a +2 longsword in her right hand and a +2 RETURNING throwing/hand ax in her left.
She gets five attacks every two turns (3,2,3,2). Her first roll (longsword) is a one, before the 3e confirm rule, she had to roll to determine what happened she rolls, a one - throwing her longsword down the hall.
Her next next FIVE attacks are natural 20s, all made from her left hand in melee mode - she was so pissed off she forgot to change hands or throw her ax. She cut a swath of destruction that caused the bugbears to fail their morale and turn tail.
The corollary is that every time she starts rolling poorly, everyone tells her to throw her weapon down the hall.
