Paris Hilton: this is her fourth fragrance

Guests on Letterman usually complain they've barely got started when they're interrupted by an ad break.
Paris Hilton must have been praying that something of the sort would deliver her from the host, who turns her slowly on a spit over a low flame on the subject of her jailtime. After about four minutes she manages to summon the nerve to say "that's all behind me now. I don't want to talk about it."
"Well, that's where you and I are different," he says. "That's all I want to talk about..."
Then when she does manage to get on to the subject of the product she has come on to plug it gets even worse for her.
