...when you're in your Chemistry class wearing your Rochester United Robotics (RUR) shirt and people ask you: "Why does Stoney Creek have 1037 people, and Rochester has 201, and Adams has 245?"
...when you're playing black jack and your total is 10 and the cards that make up that total is 3 and 7. So,... 10 3 7.
...when everyone in your class all of a sudden sees your RUR shirt and everyone starts to notice the robotics team and even asks questions on how to join.
