A question I've been asking myself is this: Why was Ann Coulter even invited to Rob Lowe's roasting? If you're unfamiliar with the term, it is simply an event where people get up on stage and tell insulting jokes about someone prominent. That someone is on the stage with them, just taking shot after shot before he is allowed to return the favor.
