Roseanne is back to her not-so-old ways, yet again, following the cancellation of her eponymous sitcom, and she's repeating the offense that got her fired in the first place.

Taking to Twitter, of course, Roseanne has retweeted some more unfavorable comments about President Obama's former aide Valerie Jarrett, whom she likened to "Planet of the Apes," not too long ago in a racist rant.

One of the tweets the actress reposted to her timeline read, "You didn't cause any pain. Those people always hated you. Valerie Jarrett wants Israelis and Jews chased into the sea, and she'll celebrate."

"Another user expressed her support for Barr, tweeting, 'Do you not know what VJ has done? Her tweet is nothing in comparison. And her tweet wasn't bullying.'"

Roseanne replied, "they know not."

This all remains a confusing move on Barr's part, who has explained to her followers that she begged ABC not to cancel her show. Seems like you can't teach an old dog new tricks after all.
