Twitter threat: "A grand wizard like you Scott Baio should be put down and someone will put you down. You, your wife and kid. Easy to find your house Scotty boy and finish you."
The Twitterverse went HAM on Chachi after he posted an unflattering photo of Michelle Obama with the comment: 'Wow - he (Barack Obama) wakes up to this every morning.” Democrats weren't too thrilled with the comment and accused the actor of being a racist.
