Whether or not you think Rush Limbaugh is a big fat idiot, it’s hard denying Al Franken’s comedic injection in the yapping-head sphere of pundits. His stand-up style jabs at the right have heralded the left’s new strategies in rousing itself through humor. Heard three hours daily on 1360 WCHL, his nationally syndicated Air American radio program The Al Franken Show will be broadcast live from UNC’s Carolina Union Auditorium from noon-3 p.m. on Wednesday, April 13. Admission is free and limited. For information, go to www.wchl1360.com.
