Believe it or not, not all of Ben's free time is spent lying to his parents and doing things he's not responsible enough to be doing. For example, today he's doing exactly what his parents think he's doing - in this case, riding his scooter around the park.

Then he almost gets hit by a rogue frisbee.

"Hey-!" He ducks out of the way and watches the disc land on the ground, then goes to retrieve it, turning to face the direction it came from. "Hey, whose is this?" He's not actually angry so much as faintly irritated. It didn't actually hit him, right? Could've been worse.
