I have one. Got it on my 30th birthday. It's on my right shoulder. It's a pic of the globe with the continents and a peace sign superimposed over it.
I showed my Dad and he rolled his eyes, groaned and said, "Bad enough you got a tattoo, but you had to go and get one SO liberal???!!!" When he said it, we both stared at each other and just busted a gut laughing about five seconds later.
