既往不咎

既 = 旡 + 艮 : Mnemonic symbol: the saying 一言既出，驷马难追 means "lit. once said, a team of horses cannot unsay it (idiom); a promise must be kept". Thus, I'll represent this character with a team of four horses.

Joan of Arc made a bet with a team of four horses that she'd be able to chew 20 chewing gums at once. After stuffing ten of them into her mouth she's already chocking, but what has been said cannot be retracted by a team of four horses.

往 = 主 + 彳 : Willy Walrus sold a black sneaker to the Lord inside of the anglepod, but the Lord is not satisfied at all. In fact he is so unsatisfied that he kicks both Willie Walrus and the sneaker towards the door.

往 = 主 + 彳 : Willy Walrus sold a black sneaker to the Lord inside of the anglepod, but the Lord is not satisfied at all. In fact he is so unsatisfied that he kicks both Willie Walrus and the sneaker towards the door.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.
