Reading Passage
It was the day of the school talent show, and everyone was buzzing with energy. Tyler, however, was acting like a chicken with its head cut off. He ran backstage looking for his shoes but forgot he was already wearing them. Ava giggled and said, “Tyler’s got a few cards short of a deck today.”
When it was his turn to perform, Tyler put a banana on his head and said it was his lucky hat. The crowd laughed. Ms. Reed whispered, “He’s not playing with a full deck, but he sure is funny!” Later, Tyler danced across the stage like a balloon without a string. He sang to his shoe and then bowed as if it clapped for him.
After the show, he told everyone that his shoe had stage fright. “That boy has bats in the belfry,” said the janitor. Maya added, “He’s totally off his rocker but that’s what makes him awesome!”
Back in class, Tyler kept humming to a pencil. The teacher looked at him and said, “Maybe he’s just got a screw loose.” Everyone laughed, including Tyler, who said, “I guess I’m just a little loopy today.”
