The Madlab Theater in Columbus Ohio is having an "undressed" rehearsal for its latest presentation of Full Frontal Nudity's "Sketch You Can Believe In" on Wednesday, January 21, 2009. While the performers will be clothed, the audience will be entirely nude.
Details are somewhat sketchy. One can assume that anyone willing to be nude in the audience will be admitted.
