What's the secret to pulling off a good prank? The naughty Chelsea Handler explains. "I don't like to do things on obvious days, like April Fools' Day. I would probably take the day off just because people are usually expecting it," she tells Rachael, quickly adding a warning, "but I would still watch your back if I were you though!" Chelsea admits that she often keeps herself busy around the offices of her E! Network show Chelsea Lately by playing tricks on the staff. "I like to send emails from people's accounts when they're not at their desks. You know, coming out to their parents or announcing a pregnancy with a one night stand. I like the reactions because I'll cc everyone in the office and you walk down the hallway and see people as they click open the e-mail!"

Rachael asks Chelsea if she consulted with family and friends for their opinions when writing her latest book, Chelsea Chelsea Bang Bang. "Absolutely not!" she answers. "My father wanted me to pay him $25,000 to use his photo in my book. I said, 'I don't think so, buddy!' He said, 'I can sue you for using my likeness and telling my story.' I told him, 'Nobody cares about your story, first of all, and you can't sue me for $25,000 because you would have to borrow the money from me to sue me!"
