Kathy Griffin's hit a rough patch of late. She recently lost in her third bid for a Grammy for Best Comedy Album, this time to Lewis Black. Last November, Bravo announced it was canceling her Emmy-winning reality show My Life On The D-List after six seasons. But her heart will go on -- to Broadway, naturally. She'll make her debut there next month for a short run just long enough to be eligible for a Tony nomination. First, she returns to D.C. for some stand-up laughs. Friday, Feb. 25, and Saturday, Feb. 26, at 8 p.m. Kennedy Center Concert Hall. Tickets are $44.50 to $62. Call 202-467-4600 or visit kennedy-center.org.
