I've helped several people remove lugs that were clearly put on by a tire shop with an impact gun and in some cases we actually DID have to resort to the "find a 300 lb guy and ask him to jump on the wrench" method.
This frustrates the hell out of me because the whole goddamned point to having a spare tire is to be able to change it yourself in an emergency. The whole concept of a spare tire goes out the window if someone has to call AAA because some idiot torqued their lugs to 5 million lb-ft.

Add a $3 piece of pipe to your tire kit. Instant cheater bar. Now a 90-pound girl can remove your torqued-to-f*ck lugs. I know, because I've given a piece of pipe to a few 90 pound girls for that reason. Oh that sounded bad.
Also for you correct torque nazis. You know that normal clamping force variation with torque-only tightening control is 40 percent right? Why do you think all the really important ones (like the cylinder head) use torque-angle tightening control? Oh, and torque settings do not account for run-down friction either? Hope the nut or its mating surface isn't pitted or corroded, you know, like a used one...
