For 17 days, the guys changed the size of their mailbox near their home to prank the postman.
YouTube creators from the Vlog Creations channel spent 17 days changing the size of their mailbox to see if the postman would notice.
At first, they gradually reduced the size of the box, but the changes only became noticeable on the seventh day.
Even when it became tiny, the postman continued to carefully deliver letters.
In the finale, the creators installed a giant mailbox. Ultimately, the postman had to pull out the largest letter of his career.
