During his guest appearance on Watch What Happens Live! this past week, Anderson Cooper switched things up and decided to grill host Andy Cohen on a series of questions for a special one-on-one interview before the two headed off to Boston over the weekend for their “unscripted, uncensored and unforgettable night of conversation.”

Questions the silver fox asked included:

Which star’s entourage has annoyed Cohen the most?
Does Cohen think AC’s giggles too much?
Has Cohen ever hooked up with someone in his office or in the WWHL Clubhouse?
Would Cohen rather have sex with Cher or Madonna?
Hillary Clinton or Michelle Obama?
