Playing a game...what would these two people talk about?

Snoop Dogg and George W. Bush, Tina Turner and Bill Gates, Mike Tyson and Paris Hilton, Madonna and Paul Reubens "Pee Wee Herman", Elton John and Rosie O' Donnell, Star Jones and Hilary Clinton, Jeff Foxworthy and Charlie Sheen. What would you think these people would be talking to each other about? Name something for each pair of people talking about something. LOL
