I am working on getting my magician's degree so that I can make all of these returns disappear.

I had a client that ran a goat's milk farm.  I thought that was unique.

I have a client that makes leather purses / wallets / belts, etc  Guess where all my fees I charge him go....

One of the more interesting professions of my clients is a young lady that is a social media influencer.  She makes quite a bit doing that. 

We had a college student doing that.  She sold it off after a year or two for 6 figures.  After she sold that one, she started a new internet gig.

My best was a Ferrier. He worked the local race tracks and fairs shoeing horses. 

I also had a client that sold clothing, appliances and things for a virtual world way back in the early days of the internet. Not uncommon now, but then it really seemed weird to me. He made good money doing it. 

I once had an arms dealer operating in the Middle East. 

My farrier retired.  For years I spelled it ferrier, because it comes from the Latin word for iron.  They put up with me but I finally admitted my mistake. 

Wikipedia says for ferrier, "Not to be confused with farrier, a profession that specializes in hoof care (notably horseshoes)."

And Merriam-Webster online says a ferrier is a ferryman.  Like, women don't know how to cross rivers?  Or, it's an obsolete spelling of farrier.
