I like to sail, and always wanted to "round the Horn" of South America. Figure if I ever do I will get my left ear pierced to mark the occasion, even though I am a straight laced type of guy.
I do have one tattoo on my upper arm from my younger, stupider days. Last year I got a flu shot and the nurse sees the tattoo as I roll up my sleeve and cheerfully asks, "hey, what's that?" I replied, "a mistake."
I have been considering having it covered with something less dorky, but some mistakes we just have to live with.

"I cannot undertake to lay my finger on that article of the Constitution which granted a right to Congress of expending, on objects of benevolence, the money of their constituents." -- James Madison
