Double Jeopardy

The answer is--

First Girl:  "Oh my god, Melody, your bottom has completely recovered from the spanking Dr. Ken gave you."                                      

Second Girl:  "So has yours, Michelle.  I'm surprised....it was soooooo red!"

First Girl:  "Yours was redder."

Second Girl:  "No, yours was!"

First Girl:  "No, YOURS was...."

And the question is:  "What would Dr. Ken like to overhear at the upcoming 20-year anniversary Crimson Moon spanking party in Chicago this coming July?"
