Cosby - Season 1 - Eps 20: That Darn Cat
When Ruth and Pauline ""just happen"" to spot a used pregnancy test in Erica's garbage and then ""just happen"" to see the positive results, they assume that Erica is expecting, but Hilton comes to another conclusion. It's bad enough that Erica has temporarily moved in with her folks while her new Manhattan apartment is being renovated, but Hilton is allergic to her cat. Then, when her married friend Stephanie comes to visit and leaves her positive pregnancy test in the garbage can -- everyone reacts in the wrong way. Ruthie and Pauline think that Erica's having the baby, Hilton is proud that he and Ruth are going to be parents again, and Ruth and Hilton end up thinking that Griffin is actually the father of Erica's nonexistent child.
