Duct tape is famous for it's ability to fix pretty much anything.  Heck, I've even seen people make clothes out of the stuff!  Personally, though, I've never thought to reach for the duct tape when I can't get a stubborn jar open.  Then I found this video, and I was enlightened.

Far and away, I have the most trouble re-opening soda bottles.  Even if I was the one who closed them, it's like the fridge screws them on tighter when I'm not looking.  Well, Fridge, your days of torturing me are done, now that I've seen this!
