A political rally

"Excuse me, miss, are you in favor of nuclear weapons?" a bubbly blonde asked the walking sunbather.

"Uhh, no. Of course not!" Mackenzie shot back.

"Perfect, we're protesting their proliferation. Here, take this shirt!"

Before Mackenzie even had a chance to read what the shirt said, she felt a tug forward as it was pulled over her head and onto her body. Looking down, it was a white shirt with the text "Fall back, not fall out!"

Not quite understanding what it meant, she then saw the blonde lift her leg up and put it through blue shorts that had the peace logo prominently emblazoned on it.

"Usually we sell this merch, but you look like you could use it for free!" the blonde explained.

"Uhh, thanks," Mackenzie was too shy to explain her new naturism. She saw a crowd of protesters with signs, and realized what she had walked into.
