Brothers Rent Billboard to Prank Dad on Birthday

Remember that ONE birthday that someone went above and beyond for you? Well for Chris Ferry, that birthday is this year; his 62nd.

His two prankster sons hung a billboard on a busy Atlantic City highway, complete with their old man’s cellphone number and a message urging strangers to call and wish him happy birthday.

He has apparently been flooded with about 10,000 calls and text messages — from well-wishers, nostalgics and oversharers.
