Julia, Jean-Claude, Chris and Brooke joined Monica, Rachel, Phoebe, Chandler, Ross and Joey in a special “Friends” Sunday night, and the high-profile guest stars proved a hilarious addition to the cast. The one-hour episode, titled “The One After the Super Bowl,” compared to the best of “Friends” – and that includes last season’s hourlong sweeps special where Monica (Courteney Cox) and Rachel (Jennifer Aniston) tried to one-up each other on a double date with guest stars George Clooney and Noah Wyle from “E.R.,” and the episode where all the pals made and broke a pact to spend New Year’s Eve dateless.
