Roseanne Barr received a surprise guest during her Comedy Central Roast taping, ex-husband Tom Arnold.

“We have not been in the same room for over 17 years,” Arnold told the audience after taking the stage.

Unlike the typical roast format, most of Arnold’s comments toward Roseanne were positive and the pair even hugged after he concluded.

Even Tom wondered about his choice in making the surprise appearance, which Comedy Central officials said was unplanned until just before taping began.

“Is this really the best format to do this? Getting together with your ex at a roast,” Arnold wondered out loud.

Roseanne was clearly touched by the appearance.

“I’d really like to thank Tom for showing up. It was very brave and he was very funny,” Roseanne said when she took the stage. “But Jesus Christ how many jobs do I have to get that guy?”

It’s good to see them put the past behind them. Maybe there’s a chance for world peace after all, eh Roseanne?
