Donald E. Lacy’s one-man show deals with life on the color line—he’s an African-American man with skin so light that some people doubt his “blackness.” Mixing humor, politics and social justice with manic pacing, Lacy balances rib-shaking laughter with a poke in the ribs. F, Sa 8pm, Su 3pm. Through 6/21. $25. Images Theatre Company at the Guild Theater, 2828 35th Street; (916) 427-7715 or (916) 737-3333; www.imagestheater.org.
