Its a sign of the times from two Florida men who gave their dad a billboard instead of a card on his 62nd birthday.

Chris Ferrys sons wanted to wish him a happy birthday, but they were in the Sunshine State and he was back home in New Jersey. So they decided to rent a billboard near Atlantic City for $2,000. The display featured his face and the words Wish My Dad Happy Birthday Love, Your Sons.

Oh, they also included his phone number.

As a result, the billboard has been the gift that keeps on giving because Ferrys phone has been ringing off the hook with calls and texts, according to Inside Edition.

Every state in the union, Luxembourg, Nepal, Kenya, Philippines. ... That little island in the middle of the Indian Ocean, they tried calling me, Ferry told Inside Edition.

Kelly Ripa and Ryan Seacrest of ABCs Live With Kelly and Ryan also tried to call Ferry on the air Tuesday morning, but he missed that call. His mailbox was full.

Ferry estimates that hes received more than 15,000 calls and texts so far, according to CBS New York.

For sons Chris and Mike, the billboard is the continuation of a childhood prank they used to play on their dad.

They would always tell the waiter [or] waitress its my birthday, even though it wasnt, Ferry told the CBS station.
