A messenger delivers an invitation to Betty Boop to come over to Grampy's house for a party and bring the gang. The delighted Betty goes down the street singing "I'm on My Way to Grampy's" and is joined by a fireman who is rescuing a damsel-in-distress but tosses her back in the burning building in favor of following Betty...anywhere; a policeman who deserts his traffic-directing at a busy intersection; and two moving men. Betty and her gang arrive at Grampy's, and Grampy shows off a few of his Rube-Goldberg inventions while serving punch-and-cake. Betty thinks the party needs a little music, so Grampy employs several of his contraptions and devices, and all hands are soon dancing to the Hoosier Hotshots' version of "Tiger Rag."
Betty Boop and Grampy
Two piano movers, a fireman and a traffic cop all drop what they're doing to join Betty Boop at the contraption-happy Grampy's eccentric party.
