Business cards

I have two sided business cards, on one side I have all my information on it with my name, mailing address, phone number, email, and website. On the other side, the printer suggested that you put some sort of personal saying or slogan, and I just put my website address on the back of it. Honestly, what the hell am I going to put on the back of my card? Fucking shit up since 1985? A costumer that can dress herself? I don't have herpes...yet?
