Time's up!"Charlie (Charlie Day), still hoping to have a child with The Waitress (Mary Elizabeth Ellis), remarks, "We don't really have any history of misbehaviour at Paddy's Pub."Mac (Rob McElhenney), oblivious to his sexual double-entendres, announces he's ordered a life-size sex doll because he "needed something Dennis-shaped to fill his hole."Frank (Danny DeVito) is using lemon juice to close up a wound.It’s Always Sunny in Philadelphia Season 13 promo banner.
