'Hopper Deck' is a deck of cards each containing a WOD.
One person will blindly draw a card from the deck and read it out to the group. If everyone in the group agrees then that is the WOD the group will do. If anyone in the group wants to draw another card the group does 10 burpees and another card is drawn.
The group continues to draw cards until they all agree.
Each person can only opt to redraw once
