Ralph Roberts, Comcast’s founder, celebrated his 90th birthday with a crowd of fellow Comcasters today. The cake was prepared by everyone’s favorite Cake Boss, Buddy Valastro, and music was provided by a group of people as distinctly Philadelphian as Ralph himself, the Mummers.

Happy birthday, Ralph!
