British "Daily Show" correspondent JOHN OLIVER became a household name when he traveled the ocean blue to land at Jon Stewart's media empire in 2006. When this incognito muckraker isn't illuminating the hypocrisy of grimy American politics, he's cracking audiences up with his original stand-up material. The seasoned comic has proven he's got the chops to decamp the Stewart kingdom, as evidenced by his 2008 Comedy Central special "John Oliver: Terrifying Times" and his recent film role as Dick Pants in The Love Guru, alongside former "SNLer" Mike Myers and recent "SNLer" Justin Timberlake. Oliver performs two shows at the Punchline. $25. 8 and 10 p.m. 280 Hilderbrand Drive. 404-252-5233. www.punchline.com.
