I've been on a nuke sub, some of the food, mayonnaise for instance, comes in jars.
ok... took me a bit, but I got it...
as a bit of advice -
you know those wide rubber bands that come on vegetables?
Save ‘em. When you get a tough jar lid, put the band around the lid and it will come off far more easily.
That took about 30 seconds to sink in then I laughed my butt off. I’m in my office so I had to pretend to be coughing. Lol.
You must live with a woman (or with more than one woman).
Hopefully not a sub.
