Today (Nov. 10) would have been Big Pun’s 40th Birthday. Although the super-lyrical MC died on February 7, 2000 with only one official solo album released before his passing, the Bronx-native left an indelible mark on hip-hop. In honor of the rhyming abomination's born day, XXL asked Terror Squad brethren Fat Joe to pen a birthday card to his best friend and the man he calls the greatest rapper ever.
