If you like this idea, it can be easily adapted for use in the classroom and can be a great way to build relationships with your students.
You can use little-known facts about people like we are, or you can use pictures of you in front of different places on vacations, short trips, at parks, etc. Write 1-3 clues about where you are, and then have students guess your location. They could bring in their own pictures, write their clues, and then submit it to you to display and play for the first 5 minutes of class.
