If you read the story the joke made sense and actually was a true anecdote.
Press was following Rush around. Rush joked they’re following you Rudi. So Rudi said actually they just want to photograph her panties.
Makes sense as a story to me.
Wie profits immensely from her sex appeal, which she enhances with her choice of attire, then is “shocked, shocked” that someone notices. Kinda like black rappers making millions selling songs to white and asian kids that are filled with “ho” and “n*gg*”, and then accusing them of racism and misogyny when they repeat the lyrics.
