"'Imponderabilia'... requires two nude performers to stand opposite each other in a slim doorway that visitors are encouraged to squeeze through to enter an adjoining gallery."

"According to his lawsuit, [the performer John] Bonafede was sexually assaulted seven times by five museum visitors.... Mr. Bonafede said in legal filings... that MoMA officials 'turned a blind eye' to the assaults and created a hostile work environment where performers were expected to submit to the actions of unruly audience members.... [T]he exhibition was grueling for many performers. Some participants reported fainting in the galleries.... Others complained that guests were inappropriately touching their bodies and making rude remarks about their appearances.... If visitors were uncomfortable passing between a naked man and woman, they were allowed to walk through another entryway to the left and skip the experience...."
