What happens if you are on a table, facing a direction that is only 2 spaces from a wall and the "Swing from a chandelier" action comes up? The card doesn't state that you "must be able to move 3-5 spaces", just that you must be on a table. And it's a purple banner, so you can't be prone. So the action isn't canceled, necessarily. Do you plow into the wall? Do you just stay where you are and spend the time ineffectually?
