How to run this drain pipe?

[wonderplumb]

On my first day as an apprentice I was told the 3 rules of plumbing.

1- ???? flows downhill

2- pay days thursday

3- all bosses are ?????

My 3 rules were,

1- Dont chew your finger nails

2- Do as I say not as I do

3-(a) The boss is always right.
(b) If the boss is wrong, refer to clause (a)

Totally Off-topic but I work as a graphic designer and would enjoy doing a design for a plumber - I have a slogan in mind and so forth so if anyone knows someone who is starting out or needs a design created just sing out.
