Keith Olbermann defended Jennifer Aniston against Bill O'Reilly's claim that her comments about single motherhood are "destructive to society."

Olbermann named O'Reilly one of his "Worst Persons in the World" Wednesday night for arguing that Aniston's comments diminish the importance of fathers and teach teenage girls that they don't need men to have a family.

But he also hinted that the reason behind O'Reilly's comments may be that he was abused by his own father as a child.

"There's been a lot of amateur psychoanalysis about what O'Reilly is doing this time," Olbermann said. "If you read Marvin Kitman's biography of O'Reilly, it's pretty simple. Virtually every reference O'Reilly makes to his own father describes how the man hit, slapped, punched him. As Ktman put it simply, 'O'Reilly has a history of physical abuse from his father.' It is actually very sad."

Aniston is starring alongside Olbermann's pal Jason Bateman in the upcoming movie "The Switch." Olbermann described the film as "Jason Bateman's new film" Wednesday; he previously used the "Worst Persons" segment to defend Bateman against accusations made by Us Weekly that he cut in line while waiting for the iPhone 4.

Olbermann made a similar reference last year; naming O'Reilly one of his "Best Persons," Olbermann said (via):

"In his nightly round of self-applause last night, designed to drown out the echo of Daddy hitting him..."
