Requests and Dedications

Last week, Sus' mom asked Sus to ask me what the expression "To have one's work cut out" means. Sus pointed out that it would take roughly ten seconds to find the answer on Google, but   Sus' mom knew that my answer would be way cooler and more entertaining that any old Google search. Sus' mom, I shall not let you down. Or I might. No way to tell yet.
My first thought was that it probably came from cobblers or tailors, and that it meant that all the material's been cut, it's ready, it's hanging over your head like the sword of Damocles, and there's no going back now. 
I'm probably right, according to WorldWideWords.org. Okay, well not a terribly entertaining answer. 

There. Now I've finished the work Sus' mom cut out for me.
