HAhahaha dont feel alone there I spilled a whole can of SparUrethane on my floor too. Atleast it will endure the harsh sunlight and outside elements for time to come. Just wear old fashioned Football spike shoes ahahahaha.
I don't have a picture of it, but I had (lost in move) a block of wood - a piece of 4"x8" with a few holes cut in it. One would fit a pint can, the next a quart can, then three different sized of "flat" cans, the sort that solvents come in. The block of wood was heavy enough that you had to really WORK at knocking it over.
Made it after I knocked over a particularly hideous shade of paint, and "painted" three weeks worth of work. Of course, the paint absolutely refused to be removed.
