In 1971, Boston After Dark (the alt-weekly that would eventually become the Boston Phoenix)
investigated a particularly whimsical outburst of art activism: Way
before the days of Banksy, six rogue Boston artists invaded the MFA's
men's room, transforming it into a makeshift gallery. They smuggled in
their own work -- via the "Is that a painting in your pants or are you
just happy to see me?" method -- and converted the lavatory walls into
"the only place in the Museum that exhibits contemporary local art."
