Test Pits - AKA - good god I need a shower

So I promised test pitting pics for anyone who want's to see me actually working, but it didn't really turn out to be that kind of a job today (perhaps tomorrow). So I give you "This is how dirty you can get at work on a good day" pics instead.

Note the happy expression of a job well done. Yeah, I know this is a really flattering picture..

Layer of dirt on the arms..

And finally, your favorite and mine... the caking of dirt in the neck folds. I couldn't wait to get in the shower!
