You will do just fine with one of the "approved" tattoos:
http://www.whitehouse.org/homeland/tattoo.aspABOUT OPERATION MANDATORY PATRIOTIC TATTOO: As part of the Office of Homeland Security's broad, discretionary power to enact any and all initiatives which may or may not prove effective in America's ongoing fight against terrorism, Governor Tom Ridge has unilaterally passed into law legislation requiring American citizens to obtain an exciting new breed of tattoo. Modeled on the ubiquitous Universal Product Code (UPC), the Subcutaneous Patriotic Intelligence Tattoo System (SPITS) acts as both a unique identifier and a satellite-trackable global positioning device, enabling the wearer to rest easy in the knowledge that s/he is quantifiable, qualifiable and locatable by the federal government at all times.
Every American will have their choice of any of the three exciting SPITS executions pictured at left, applied under sterile conditions by Federally appointed tattoo technicians - beginning in early February, 2003.
All citizens will be afforded ample opportunity to affirm their patriotism by proudly submitting to this brief and only mildly excrutiating procedure. Any and all able-bodied persons who miss the mandatory tatooing deadline of July 4, 2003 will be subject to fines up to $75,000 and/or terms of medium security imprisonment no shorter than 2 calendar years. The Office of Homeland Security strongly urges any individuals who oppose this right-minded defense program to overcome said opposition, thereby assuring uneventful compliance and significantly reduced post-procedural trauma.
