Ah, where do I begin? According to my husband I have several. Amazingly enough they all seem to be in the same spot. Depending upon his mood he will tell people I have the Titanic or the Bismark on my ass and can make it sink. Sometimes I have Darth Vader and Yoda fighting. And of course the old "MOM/WOW" trick. I actually don't have any and never will!
I once started a rumor about a bank teller's tattoo (she actually didn't have one).
It was a tattoo of John Holmes; it started on her hiney, and continued down her leg.
The funny thing was that she was innocent enough that she did not know who John Holmes was when I told her what kind of tattoo I was going to tell she had (long story). When one of her co-workers filled her in about John Holmes....uhh...attribute, she thought it was hilarious; gross, but hilarious.
