If you are using cheesy clip art, razor thin paper or perforated print at home sheets then you need new business cards. Have fun and experiment. It's your card and you can make it however you want. If your company makes your card, make your own set and hand them both out. Just because your company is boring does not mean you have to be.
Can your card be identified in a line up? Does it stand out? Does it tell people what to do next?
