The Silly String took over Joey’s brain when he was eight. He didn’t mean for it to happen — I don’t think anyone even knew it could happen. He held the can up next to his nose and pretended to sneeze the string out, as people do, but he goofed and inhaled. His mom took him to the emergency room, but the doctor said he couldn’t see anything wrong with Joey.
His grades got better after that; he could finally string his thoughts together.
When he grew up, he went to work in a gag factory. He’s working on upgrading himself.
