LARRY THE CABLE GUY has the country-bumpkin act down to a science. As the most popular personality of the original four Blue Collar comedians, Larry the Cable Guy's simpleton charm has won over audiences across the nation. To borrow some one-liners from him, if you see his show, you'll be "happier than Heidi Klum's gynecologist," but if you miss it, you'll be "madder than a legless Ethiopian watching a doughnut roll down a hill." $44.75. 5 and 8 p.m. Fox Theatre, 660 Peachtree St. 404-817-8700. www.ticketmaster.com.
