Tom Arnold wasn't on the dais for the Comedy Central Roast of Roseanne, but he certainly took a fair share of hits over the course of the night. While he reportedly had "no interest" in appearing on the roast, Roseanne's notorious ex- took the stage late in the show, announcing that it was the first time they had been in the same room in 18 years. After delivering a few jokes — "she may not be a perfect wife, but she is literally the worst ex-wife on the planet" — Arnold then gave her what was perhaps the most moving and genuine tribute of the night.

Watch the end of Arnold's speech above and then catch up on what else you missed on our live blog.
