I have zero tattoos, but I like them. I really do. I appreciate well-executed tattoos that are works of art.
I would get a tattoo but I can’t commit to a design or a place. Last week I dreamt that I got a tattoo on my arm and it was awesome. Then, (also part of my dream) the next day I freaked out because it was permanent and so “yesterday.”
So when I saw the story of the man who accepted $15,000 from a Republican to tattoo the Romney-Ryan campaign logo on his face, I instantly agreed that he belongs on Anderson Cooper’s RidicuList. See for yourself: CNN – Romney face tattoo
Laughing is required. 
Better question for yourself: why?
Why what? Why can’t I commit to a tattoo?
Why do you want a tattoo on you?
That is a better question.
I as well have no tattoos for more or less the same reasons you don’t.
Plus I have seen too many that 10 years later are not so hot looking.
