Surprise :-) The fridge/freezer in our office is frozen into a solid block of ice ... . Well, I guess that´s what it is made for.
But now you can´t get anything out of it without an ice axe. :-/
We cannot defrost it, as we have nothing to collect that much water. And it is to heavy to carry, with all that ice in it. And no one wants to ask the Janitor for a wheelbarrow ...
