Bart was hanging out on the roof of his house (yes, he climbed up the chimney to get up there) when he saw you walking by on the sidewalk. With his signature mischievous grin, he picked up a random piece of rubble from the roof and threw it directly at your head. It hit you in the head successfully, causing you to fall down.

“Ay Caramba!” Bart said. He’d thrown the rock with mischievous intent, but he didn’t expect it to hit you that hard.

“..I must be have super-strength! Like Radioactive Man!” He said, before bursting into laughter. It was clear that Bart did not give a shit about that, even if he could’ve given you a concussion.
