Macy's Thanksgiving Day Parade (2008)

Shontelle's song "T-Shirt", (non-explicity) mentions a woman being naked (waist-down), and wearing "only a t-shirt", as well as mentioning lingerie.

All these took place during the first hour, when the broadway performances were being performed:

During the performance of "White Christmas: The Musical", the women wore dresses that showed cleavage.

During the performance of "The Little Mermaid: The Musical", several men were shirtless (in a non sexual way), and the women wore costumes which revealed great amounts of skin, including cleavage. There was an incident where one of the starfish ornaments on a woman's "starfish bra", almost fell off her left breast, but she quickly prevented it.

During the performance of "South Pacific", lonely marines serving in WW2, sing about wanting/craving a "dame". The references are implied to be sexual in some situations, without explicity stating so.
