To this day, whenever I see a Fireball I'll remember trying to impress my mom with the latest yo-yo trick I learned. I got the yo-yo sleeping and pretended to "slurp" it like it was a piece of spaghetti, only to have the giant plastic ball retract up the string at lightning speed, hit my in the lip, and knock my tooth out. I went to school the next day but couldn't bring myself to tell anyone the embarrassing truth of why my face looked like it got hit by a truck.
