What I should have said was nothing.

So this guy calls me yesterday from the Chamber of Commerce. We get our labor law posters/books/pamphlets from them and he was calling to let me know about a new product that they have for the human resources department. I explained that we don't have an HR department, exactly, because we only have four employees here. Ah, yes, no need for this interactive website then, I see. I let him know that we make sure we have the correct posters displayed and that we hand out the correct pamphlets once a year, but beyond that we don't really have any HR issues wth the staff. Then I said "We're over here..." and I trailed off because I realized I was about to tell a representative from the Chamber of Commerce that "We're over here sexually harrassing each other all the time." and I didn't think he would find that funny at all. For once in my life my filter worked. Great success.
