Milt Britton and his orchestra are playing in a New York City cabaret, and an Englishman resents Milt's air of confidence, reference the band's ability to make anyone laugh, and he makes a wager that they can make a giant decoration-reproduction of the Sphinx laugh. The first two attempts fail, including a comic bit by Tito and Joe Britton, but then Britton and his band breaking into their trademark musical frenzy, and break up all the instruments including the bass violin and the piano. The Sphinx rocks with laughter.
