"Real Time" host BILL MAHER proved he had no qualms criticizing Bush-era White House policies. Now that the Bush regime has been put to pasture, Maher has moved on to the sacred cows of President Barack Obama's health care reform and organized religion. He crafted a glib, vaguely manipulative but ultimately hilarious mockery of the theistic faithful in 2008's Religulous alongside Borat director Larry Charles. Maher tackles even more controversial topics, including war, sexuality and drugs, at the Cobb Energy Performing Arts Centre. $38.50-$71.50. 8 p.m. 2800 Cobb Galleria Parkway. 404-817-8700. www.ticketmaster.com.
