A dad in Britain needed some help while working on the family car so he asked his kids to lend a hand. That turned out to be a hilarious mistake.

While it's unclear on what he's trying to do, what is clear is that it has something to do with the cars electrical system and turning the key to the "on" position will give him a good shock. A point he stresses repeatedly to his son sitting in the driver seat. A point his son repeatedly ignores.

I learned the hard way myself a couple of year's ago that kids shouldn't be anywhere near the car, much less in it when you're working under the hood. Until about a year ago, I had an old 1997 Dodge Ram. At some point, the air conditioner quit blowing cold air so my son and I took it to my uncle who is a "car guy" to see if recharging the coolant would fix the problem.

His garage sits next to his house and both sit on top of a hill. The driveway leading into the garage is uphill the whole way at not much less than a 45-degree angle and doesn't flatten out until you're actually in the garage. Anyway, during the recharging process, my son who was five or six at the time asked if he could get in the truck. I didn't think much of it and let him go ahead and hop in. A few minutes later we heard the "pop" of the engine being put in gear and the truck started rolling backwards (I didn't engage the emergency break before getting out). Keep in mind, this was a nearly 13-14 year old vehicle at this point and had about 150,000 miles on it meaning parts had worn down over time and accidentally knocking it into gear wasn't difficult to do.

To this day, I still don't know how I managed to do this, but I was able to open the passenger door as it rolled down the hill, hop in and slam my foot on the break all in the span of about two to three seconds. The truck finally came to stop in a neighbors front yard after it took out their mailbox. Fortunately, no one got hurt. Lesson learned.
