NFL Hall of Famer Art Donovan, who had a great career on the field, and then put many smiles on people's faces, with his humorous stories after his playing days, died on Sunday, at the age of 88.

Voted in the Pro Football Hall of Fame in 1968, Donovan, a defensive lineman, was a five-time Pro Bowl selection, and a member of two NFL Championship teams, while a member of the Baltimore Colts, during the 1950's.

Donovan, who's number 70 jersey is retired by the Colts, was the first player ever inducted into the Hall of Fame from that organization.

Following his playing career, Donovan became an author, television host, and humorist, appearing ten time on the Late Show with David Letterman.
