Down at Santa's Workshop, Joe walks Oprah through the first show. "There have been some moments when I've come down and looked at those sets and say, 'Wow, you should get an award for this,'" Oprah says.

During rehearsal, the crew practices dropping a box that will contain a Philip Roth watch. When Oprah reaches for it, it drops too low. Jenna and Caroline look stressed, but Oprah remains optimistic. "That's what rehearsal's for," Oprah says.

Jenna's not worried about Oprah—just everything else. "Oprah has got an amazing photographic memory, so she's going to get this nailed down," Jenna says. "But it's two shows with about 150 moving parts, so it still doesn't mean that a million things couldn't go wrong."
