The Oscars just may be filled with dirty jokes this year, because Family Guy and Ted creator Seth MacFarlane is hosting. "My two thoughts upon hearing the news were, 1) I will do my utmost to live up to the high standards set forth by my predecessors and 2) I hope they don't find out I hosted the Charlie Sheen Roast," joked MacFarlane when the telecast producers made the announcement. The Academy Awards air live on Feb. 24 on ABC, BroadwayWorld.com reports.
