The scandalous book “Fifty Shades of Grey” that was a cult phenomenon in 2011 is now judged ripe (worthy?) of parody. “We feel blessed that people think our show is as funny as we do,” writer/director Jim Millan told Folio Weekly’s Amanda Long. “We have to stop the show sometimes to let people laugh.” Millan, who directed the Canadian sketch comedy “The Kids in the Hall” for 12 years, called “Spank!” a mix of naughty and silly. The steamy parody hits the stage for six performances April 9-13 at the T-U Center’s Terry Theater, 300 W. Water St., Downtown, $49.50, 442-2929, artistseriesjax.org.
