Dotty and her friend Betty are practicing somersaults, but Betty can't quite get the hang of it. Dotty's older sister, Bernie, joins them to show the girls how the stunt should be done. Dotty resents the performance, complaining that her sister is "just a big old showoff." Betty hears Dotty's brother Morrie practicing piano and admires his skill, and Morrie responds by helping her learn to play "Chopsticks." This upsets Dotty all the more.
