1. Donnell Rawlings is familiar to fans of Comedy Central’s “Chapelle Show” as Ashy Larry, the guy who tries unsuccessfully to be a class act. Rawlings shows class at 4 p.m. today when he visits Bulger Communication Center at Buffalo State College to talk with Buffalo high school students preparing for college in the Upward Bound program. “He has a background and upbringing very similar to our students,” says program director Don Patterson. “We thought it would be a great opportunity to have him speak with these young people. As a testament to his character, he was more than happy to do so.” Rawlings also performs at 8 in LUX Night Club, 75 W. Chippewa St. Tickets are $30 and $40.
