I saw this about 1 year 1/2 ago in a trade journal we get in the office (I work for a plumbing company) and thought it was novel, but lacked good taste. How about a couple more (in)famous plumbing tag lines:
Your #2 is our #1.
We drool for your stool.
We aim to please. You aim too please!
Your $hi+ is our bread and butter.
Plumbing problems? Don't get deterred (say: de-turd) Call us.
Okay, I think that'll be enough potty humor for a bit.
