Patty is one half of Marge's twin sisters on The Simpsons. In case you get them confused, Patty is the lesbian sister that adopted a Chinese baby and has a pet Iguana.
Patty: It's almost nine o'clock.
Selma: Where is Homer anyway?
Patty: It's so typical of the big doofus to spoil it all.
Lisa: What Aunt Patty?
Patty: Oh, nothing, dear. I'm just trashing your father.
Patty: Hello, Marge. It's Patty. Selma and I couldn't be more excited about seeing our baby sister for Christmas Eve.
Marge: Well, Homer and I are looking forward to your visit too.
(Homer makes a gagging noise.)
Patty: Somehow I doubt that Homer is excited. Of all the men you could've married, I don't know why you picked one who is always so rude to us.
