in that episode was a conversation with Frank Costanza, Goerge and Kramer.
Kramer:"I thoght Jerry didn't want the couch because of the stain"
Kramer:"what, you didn't notice, it has a pee stain"
frank:"you have me sleeping in a pee stained couch?"
Goerge:"no, no, no, no, no. The cushion was turn over"
Frank:"with the very idea, you let me lieing in urine"
you have to know what episode I talk about.
God bless you, Avi L.
