Rum Tum Theta is a curious planet

On this day in 2525, a Broadway show is disrupted when an audience member from the Felinthinus Galaxy starts screaming "Blasphemy! Blasphemy! Our history tubes tell a decidedly different story!" Given that no one in the audience understood a word of Felinthinese, many assumed that this was an avant-garde bit used to liven up the show. Reviews are overwhelmingly positive, and CATS remains on Broadway for another 1,000 years.
