TK-421 Star Wars Morale Patch in Glow-in-the-Dark PVC. Classic TK-421 behavior. We all know that guy -shirking his responsibilities, leaving everybody else to pickup the slack. Never around during barracks cleanup, always an E-1 because of the DUIs, and he's got more investigations on him than Hillary Clinton. TK-421...just leave the force already. Be sure to check out the TK-421 Zippo Lighter.
