Not really my most favorite, but definitely my most memorable:

Many years ago when I was just establishing my reputation with successful word of mouth, I was contacted by a friend who said some business associates of his father wanted to hire me to videotape some depositions to be used in a trial. The amount of money they were offering was jaw dropping to say the least. I was pretty poor and needed money badly at that time, so I jumped on it, even though I had to drive to New Jersey to do it.

I followed the directions and found myself way out in the middle of nowhere, somewhere near Cherry Hill - nothing for miles in any direction except corn fields and a small shack - that was the destination. Well, it turns out the client was the Teamsters, complete with a goon squad.  The "godfather" of the group came up to me and said - "We're glad you're here, you come very highly recommended and we know you'll do a good job, BUT...(and he got right in my face and punctuated his words with his finger in my chest)...you f us up, and we'll f you up!"

I was never so nervous or fearful for my life since 'Nam. Needless to say, I made doubly sure everything went off perfectly. And I promised myself next time to look the next gift horse I'm offered very carefully in the mouth first.
