Practically speaking, it's impossible to roll 6 one hundred times in a row on fair dice. Not technically impossible, but we each get to calibrate our skepticism based on how far out the probabilities are.

In this case we can be sure the dice aren't fair because there's significant motivation for them not to be, or at least it's easy to imagine a manufacturing defect in the dice.

This is a 1 in 50 chance we are dismissing as practically impossible though.
