What is the biggest mistake?

Cleaning the inside of my truck in the garage while home on leave. Mind you this was a pretty tight space I was in. I bumped a steel crib rail my wife had precariously balanced against the garage wall..... it fell against my driver side door, scrathing it all the way down.

That was awesome

 

My buddy and I just did my AAL yesturday. My truck won't fit in my garage all the way, so I backed in far enough that my doors would still open. Jacked it up, put it on stands, and good to go. So there we were, passenger side was finished and bolted back up. We start to bang and shake and hammer the drivers side leaf springs to get the damn center pins aligned, when we realized that, well, my driveway is on a slope down from my house and well, we all know that the truck is RWD/4WD. Well I didn't chop the front wheels, and ist started to rock off of the jack stands! We just took our time and I jacked up the truck a little more on that side to help support it and put the tires in front of the tires. Nothing happened, but we were both under the truck throughout the install, and the POTENTIAL of something to happed was easily there. I just wanted to get it done as soon as possible to get the wheels back on. No worries though, but I will for sure use some chop blocks next time!!!

 

My shop teacher was working on his old corvette, which had one of those direct intake things where there is no filter and you just have those pipes that stickout of the hood to suck air. Well he started it up and was standing over it with a nut in his hand and dropped it. By some stroke of god about a millisecond later it flew out the exhaust at about the speed of light. It was the luckiest day of his life he says.

 

That's insane!!!
