Porch Coaster

Uh! The living room was dead silent, so I shoved through the front door! Hanging right from the porch ceiling was a giant wooden bench dangling on four heavy iron chains! Why is it just floating in the air doing nothing? I didn't sit down gentle, no way! I scrambled onto the slatted seat, stood straight up on both feet, and started pumping my whole body back and forth! SQUEEE-CLANK-SQUEEE! The rusty links screamed like an angry iron monster! Then I swung way back and kicked the railing with both heels! BAM-RATTLE-BOING! The whole porch shook right through my diaper and made my pencil buzz! Best swinging roller coaster ever!
