Dilbert and Dogbert play with a remote control airplane outdoors. The plane begins to move and Dilbert says, "Approaching take-off velocity . . ." Dilbert hears a "Whap! Thud!" in the distance. A man holding a frisbee lies on the ground with the model plane stuck to his head. Dilbert says, "Gee, you'd think he'd know it's reckless to play frisbee in a populated area."
