I have one really bad tattoo... It's on my ankle, it's small, old, faded, fuzzy and almost impossible to recognize. I got it as a skate punk kid way back when I was underage, in a biker shop, in 1990. It was destined to be questionable.
Needless to say I was surprised when I hesitantly showed it/ talked about it to the artists at the Pearl (while @Mark Bee and I were getting work done) not only were they enthusiastic about my weird little blotch but told me to never cover it - because old crappy tattoos (depending on subject matter of course) are their own kind of awesome. Funny that they appreciated my youthful folly - which I'm sure is helped by my acquisition of several new and particularly awesome tattoos.
Or I suppose I could always blast over it with a panther :)
