Not funny. Years ago, a friend of mine was installing some new shocks, and as he crawled under the back end to place the jack stand, the car, which was up on a jack (yeah, it was a stupid move), suddenly shifted and started to fall. Another friend pushed the car toward the front just enough to give him time to slither out from underneath. The fuel tank split open as the jack stand pierced it.
Had to call the fire department out to dissipate the gasoline in the sewer so it didn’t blow up from some stray spark down line.
The one guy definitely saved the other guy’s life, because he would have been crushed pretty flat.
True story.
(And yes, alcohol WAS involved. With all of us. How else to explain six to eight grown, and otherwise intelligent, men allowing an idiot to crawl under the back end of a car that’s only supported by a jack?)
Buy your friend a floor jack or a set of ramps for his birthday.
