The gang plans a surprise party for Rachel, but the real surprise is when both of her estranged parents show up for the same party. "Think!" urges Chandler. "What would Jack and Chrissy do?" Why, split it into two parties, of course -- one for each parent. But complications inevitably ensue.
Great episode, I was worried they weren't going to be able to keep up to the shows standards after "TOW the Bullies" but they managed to ensure every little knot was tied properly.
