Comedy Central said today that Family Guy boss Seth MacFarlane will host the Comedy Central Roast of Charlie Sheen, which will tape in Los Angeles on Sept. 10 ahead of a Sept. 19 airdate — which happens to be the same night CBS premieres the post-Sheen post-Two And a Half Men. MacFarlane has hosted two previous roasts. “In addition to his sharp wit, Seth is way more suave and sophisticated than we are,” said Kent Alterman, head of original programming and production at Comedy Central. “We continue to try and soil him.”
