Funniest man in America? I'm not sure about that. Comedian James Gregory is bound to offend some, including hardcore environmentalists obsessed with endangered species and global warming. Gregory has been quoted as saying, "If you want me to be concerned about endangered species, you need to convince me that we're about out of chickens." You can see just how funny he is when he performs at McGlohon Theatre tonight. $25. 7:30 p.m. McGlohon Theatre, 345 N. College St. 704-372-1000. www.blumenthalcenter.org.
