How would you like to be a part of the Greatest International Scavenger Hunt the World Has Ever Seen? Then you'll want to sign up for GISHWHES (pronounced gish-wes), because that's what it's an acronym for. Supernatural superstar Misha Collins started this epic international hunt six years ago, and it has since gained such fame as NASA naming a Martian mountain after it and breaking multiple world records. GISHWHES also does a lot of good for local communities, so join the fun, help your neighbors and sign up today! Registration ends July 21st.
