On the subject of changing tires,

ever had the desire to find the idiot with the impact wrench at the tire store and use the wrench on him?

While back came across someone with a flat. This was on an old Oldsmobile full-size car with the old-style jack & lug wrench that doubled as a jack handle, which gives you a lever damn near three feet long to remove the lug nuts. I weighed about 175 at the time, and I actually had to bounce on the end of the wrench to break three of the nuts loose; this was an old couple and there's no damn way they'd have been able to change that tire.

New tires, mind you(sidewall blew out on the flat), put on two weeks before. I told them to go back to that store and get the tire replaced, and tell the service manager to make sure an average human could get the damn nuts off without having to play acrobat.
