In an earlier episode Ross turns down the name Helen for his child with Carol, but in this episode it is one of his suggestions for his baby with Rachel.
In the closing credits, when Monica and Chandler are in the bath and the scene starts, there is nothing on Chandler's cheek. After Monica says, "I'm not touching you," there is some foam on Chandler's cheek.
When Chandler is in the bath for a second time, the foam in his hair changes between different shots.
When Monica presents the toy ship to Chandler, the direction the ship is facing changes between camera shots.
At the start when Chandler says, "Mon frère," to Joey, Joey says, "What?" as if he's never heard it before, but in an earlier season he says it to the Monica, Phoebe and Rachel.
