Deandra "Sweet Dee" Reynolds
Deandra "Sweet Dee" Reynolds is Dennis' twin sister and the main bartender at Paddy's. Sweet Dee was definitely considered a loser in high school thanks in part to her back brace she had to wear back then. Sweet Dee failed out of U Penn, where she studied psychology. Now, she's mostly a failed actress and stuck as a bartender with her brother and his friends.
Charlie: what is your spaghetti policy?
Dee: Are you hearing this? He doesn't belong in a place like this.
Dennis: It's because of those bison fingers.
Dee: I do not have bison fingers!
Frank: Yeah you do. Your mother had to have a c-section because of those hands.
