In I Accuse My Parents, the "action" such as it is, stops twice for treacly ballads, including Are You Happy in Your Work. Maybe this singing actress is, but we're not.
In Eegah, Arch Hall, Junior sings a lovely ballad to "Vicki". Too bad his girlfriend in the film is actually named "Roxy".
In addition to having a ridiculous title, The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies is also full of annoying songs and random dance sequences. The most annoying song in the film is easily Shook Out of Shape.
An even more annoying song is found in Teenage Strangler. Yipes Stripes. In the world of the film it is apparently the only song that exists.
And finally, The Girl in Gold Boots features a guy who can't sing and a girl who can't dance. Critter may not be certain whether he should Laugh or Cry, but you will definitely want to scream.
