“Will Ferrell: You're Welcome America – A Final Night with George W. Bush” drew HBO's largest audience for a comedy special in five years. “America” drew 2.3 million viewers, the most since “Chris Rock: Never Scared” in 2004. Saturday night's spoof of the Bush years was followed by a strong Sunday evening, with “Big Love” having its second-largest audience of the season (2.3 million viewers) and “Eastbound & Down” garnering its biggest viewership yet (950,000 viewers). “Eastbound” is also up 41 percent at this point compared with its lackluster season premiere.
