... I must start to shame my dice in hopes that they learn a lesson.
Yeah, maybe it's time for a bucket of shame for my 40K dices.
My dice love rolling high on skillchecks...and then failing abysmally once combat starts. xD
One of my gaming friends from college used to arrange his dice in a semicircle around the offending die, dab some lighter fluid on it, and light it on fire, as an example to the others.

Our 40k dices get lost often... I consider it as a form of vengeance. ( Still have about 200 though)
