So I thought I'd rotate my tires today as I was replacing the brake pads. I picked up a second set of jack stands, but as I was unpacking them I noticed a warning on the side that basically said even thinking about using jack stands to support more than one end of the vehicle at a time would doom three generations of your family to always having their bread land butter side down...
Is this just the manufacturer covering their

, or are there certain dangers/precautions/steps to doing this I don't know about?
Thanks!
