Scott BaioWith great power comes great responsibility, but former child star Scott Baio has been using the far-reaching social networking tool Twitter with reckless abandon -- again. Baio found himself in hot water last January for insulting First Lady Michelle Obama online, prompting angry threats from his followers and numerous accusations of racism and misogyny. Now, the 'Happy Days' actor and his wife Renee are locking horns with feminist Web site Jezebel.com by way of multiple Twitter posts. Baio has stepped up to defend his wife, who called the staff of Jezebel "a bunch of far-left lesbian [expletives]."

"We all have the right to exercise our freedom of speech, including my wife," he writes.
