According to Julia Louis-Dreyfus, the key to the comedy in her dancing was to look as ridiculous as possible while keeping her face full of confidence and thorough enjoyment.

In this sense, in spite of the fact that she was deliberately dancing poorly, she was going for a feeling of humiliation, as she wanted people to laugh at her more than with her.
In the opening scene of this episode, Jerry and Kramer are discussing which side of a sidewalk is safer. Jerry tells Kramer that by walking on the inside of the sidewalk, an air conditioner could hit you if it fell out. In "The Glasses" (S05E03), Jerry's AC unit falls out of its window to the sidewalk below, injuring a dog.
