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.
Dee: You've been really stressed so I thought I'd take you to a spa day. Just the two of us.
Charlie: A what day?
Dee: Spa day
Charlie: What is this word, spa? I feel like you're starting to a say a word and you're not finishing it. Spaghetti? Are you taking me to a spaghetti day?
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.
