Ross finds out his ex-wife (Carol) is pregnant, and he has to attend the sonogram along with Carol's lesbian life-partner, Susan. Ugly Naked Guy gets a thigh-master. Ross and Monica's parents come for dinner, which stresses Monica out. Ross and Rachel console each other. Rachel returns the ring to Barry, who is much less upset about the break-up than expected.

[ NOTES: In this episode, we learn that Phoebe is a twin, which explains Lisa Kudrow's continuing presence on Mad About You.
James Michael Tyler appears as Gunther in Central Perk for the first time, but has no lines. He remains an uncredited extra until midway through the second season.
Anita Barone had auditioned for one of the three female leads in the show, but didn't get the part. The producers then offered her the recurring role of Carol. However, after only one episode as Carol, Barone decided that she was looking for a more full-time role and left to look for other opportunities, being replaced by Jane Sibbett beginning in episode 9.
In the tag scene, Rachel tells Mindy that she hopes Mindy's children have her old nose. It's ironic that Jennifer Grey, an actress who is known to have had a nose job after rising to fame, would go on to play Mindy later in the season.
This episode runs 24:15 on DVD (a typical sitcom runs about 22:00). ]
