All you have to do is show up at any of the three BGR: The Burger Joint locations and show off some body part that’s stamped with the BGR logo. (See the logo after the jump for those who want to draw their own.)

The shop will even assist you in the freebie. They have “street teams” at their locations in Bethesda, Old Town, and Dupont to apply the proper stamp. But you better hurry: The free burger is only available from 11 a.m.  to noon today.

And vegetarians, you’re included in this, too. The veggie burger is part of the promotion.

Burger Joints are located at:

  • Dupont Circle: 1514 Connecticut Avenue NW
  • Alexandria: 106 North Washington St.
  • Bethesda: 4827 Fairmont Ave.
