On "Girlfriends", a favorite running gag was that Toni could never remember Maya's son's name.

My favorite one, because Maya just gives up on telling Toni one more time what her son's name is:
Toni: "Who's Jabari?"
Maya: "My son!"
Toni: "Jacuzzi changed his name?"
Maya: "No, girl, he's....yeah, girl, you like it?"
Toni: "No!"
