Televisionista: Ben Affleck & Jennifer Garner @ Falls Church High School's Graduation

Movie star Ben Affleck and his wife Jennifer Garner (TV's "Alias") made an appearance at Falls Church High School Graduation ceremony on Friday where Ben gave a speech cracking jokes about his film career and giving a heartfelt tribute to a graduating student he befriended years ago.

Students at Falls Church High School and family members gave a standing ovation to Affleck following his commencement speech, in which he praised 19-year-old Joe Kindregan, a disabled student he met in 1998 on a film shoot at Dulles International Airport.

The two met when the Kindregans came to Dulles to watch a crew shoot the film "Forces of Nature." Affleck noticed Kindregan, then 10 years old, in his wheelchair and started a conversation. The two built a close friendship.

Kindregan introduced Affleck to the audience by saying "He is married to the cutest girl... but most important he is the best friend you could ever have."

"Everything I learned about life that really matters, I learned from Joe," Affleck told the audience.

Kindregan suffers from a rare, degenerative genetic disease. Over the past decade, Affleck has helped Kindregan raise money to develop a cure for the disease.

Affleck said Kindregan has since been on the set of all of his films - "He liked being on the set of 'Daredevil' a lot more than being on the set of 'Gigli.' But he was too polite to mention it," Affleck said.
