I still want to know what happens if you put a can of sardines in the freezer. but I suspect that you just get sardines that are frozen solid. I don't think that the can would burst. Otherwise, all those old guys in Norway who row boats and chew on old sardines would starve to death.

but who knows?

I prefer that someone else explode frozen sardines over THEIR refrigerator. that's really why I asked :-)
