When you don't chock a trailer before unhooking it - GIF

Man, that must have been a REAL drag.

The trajectory of the trailer couldn't have been more perfect, missing the light pole, trash bins and other vehicles before gently teeing into the curb... I imagine it would have been a different outcome had he not provided the extra resistance. I don't think I would have trusted my well-being to the wheeled jack, as it could have easily failed under those stresses and crushed a hand, or worse.

I knew a fellow years ago who was working at a soldering station... he accidentally knocked his soldering iron over and it began to slide off the bench... reflexively he caught it by the hot end as it was falling, and thus got scarred rather badly. Sometimes it's healthier to just let things go.
