After my first real day at the water plant

This is the best line someone could hope for the first day on the job at a wastewater facility:

Derek, the guy showing me the ropes:
Ok, you don't need to brown-nose or nothing, but keeping this lab clean would earn you serious brownie points since you are new here and you don't know shit yet.

I asked if there were any puns in that last sentence, and he just gave me a confused look. Oh well. I forget what he said I'd be doing tomorrow, but it involved the words "mucking" and "solid," so I won't be wearing nice clothes.
