Make Zack fly

Zack, on his way to his bedroom stopped and turned, “You’ll do what?” Brad went up to Zack and pulled him back into the living room. Alex just watched from the side lines.

Zack still confused asked, “How are you going to make me-“ he was cut off because all of a sudden Brad grabbed the back of his boxers and gave him a giant wedgie. The kids erupted into laughter. Zack tried to fight it, but the more he fought the worse it became.
