Anyone need a Tow strap?

I was at work the other day and noticed a seat belt in the trash can. I guess it didn't retract anymore and had to be replaced. So I took the seat belt and added a couple of hooks to each end and all of the sudden I had a new Tow Strap.

I found that it worked pretty well for just pulling cars, but when I tried to use it to pull out a tree stump it snapped in the process.
