Let me preface this by saying that I have an awesome wife. For instance; by profession she is a firearms instructor for a very large federal agency and can spank most men with a hand gun with one arm, then tear the guns apart and put them back together, all while explaining what all the little pieces do. Really! She's cool!

Doesn't look like a gun person does she? LOL
That being said, I learned early on in our relationship that I don't want her helping me in the garage.
Lesson #1: I asked her to sit in the driver's seat and hold the brake with the car in drive. MY bad. The master cylinder was starting to go and would leak down over time. I warned her of this and told her that if this were to happen then to quickly pump the pedal once and all would be fine. Well I took to long, the pedal leaked down and she couldn't do anything but push harder. That didn't work. That car rolled forward into the body of a 70 Boss 302 and pushed that into the house.

OK, that was stupid on my part. I shouldn't have expected it to go any differently.
Lesson #2: While removing the top loader from my other Boss my plan was to use a small 1 1/2 ton jack to hold the trans while pulling it back and then lowering it. This was well before the days of my having a lift or trans jack or anything you might call correct for the job. So there I was under the car balancing the trans on the little jack pedestal and asked my beautiful, blonde,

gun toting, future bride to pull the jack handle toward the rear of the car then lower it when I said to. OK, I asked her to pull it to the rear ...................which she did, with all of her considerable might. Right out from under the back of the car without the trans. Has anyone ever tried to lay on their back with their arms outstretched over their head?...........holding a top loader by the input shaft and tail shaft. Yes, there was a loud CLANG as the trans dropped to the floor.

That was my last wife/garage lesson.
The only other lesson that I apparently needed was the; “when she’s slamming cabinet doors in the kitchen after saying that she was hungry a half an hour ago its time to take her out to eat no matter how much grease you have on you” lesson.
We’ve gotten along great since I learned that one!
