I work construction and I will avoid my own stories because of the yuck factor here are a few I have witnessed over the years
The plaster spread between sheetrock comes in big 5 gallon buckets people always use them as toilets I have learn the hard way never to grab a bunch for home projects if they have lids on them as you get them home and open them and yuck
Seeing that someone shit in the corner on large jobs is not an unusual thing yuck
i like that you said "yuck" three times 
my stories arent even graphic or disgusting, i think people just assume they will be, and dont even dare read them >:I
I think you posted too many in the first post. You should have spread them out over the entire thread.
Smeared Shit 
probably, but the numbering should indicate theyre many _short_ anecdotes, and not
one continous and vigorous description of poop in all its forms.
oh god now people will skip to page two, and theyll catch ^^^
and theyll assume thats whats on page 1
