Actual answer.

You would set up milk crates getting progressively one crate higher up and then back down in a pyramid and try to get from one side to the other.
The physics of it fucks you, since going up is easy, the crates push against the stack in from of them and their combine resistance makes it easy. When you try to come back down, the crates are super light weight and have nothing to lean or push against so unless you are very careful about stepping down directly in the center with no forward momentum, they fall forward and you fall down onto a bunch of milk crates or floor.

So challenge in that its basically a carnival game that is designed to make you lose and get humiliated but with no stuffed animal for doing it right.

Wow.

And not like a good wow. Thats a very concerned for your mental health and what you interact with, wow.
