When Frasier’s car breaks down, the entire Crane crew hitches a ride with a pregnant taxi driver, Arleen, who suddenly gives birth. This unexpected event amazes Frasier and Martin, but terrifies Niles.

Later that night, Niles works through his fears and decides it’s time to practice being a father to a sack. His dreams of paternity are dashed, however, when the “healthy” sack of flour transforms into a battered, nearly empty one while in Niles’s care.

At the station, Frasier accidentally signs a birthday message in a card for a dying radio station security guard. Frasier manages to steal the card back, but when he tries to deliver the replacement card, he gives it to the wrong patient. While at the hospital, Frasier runs into the security guard, who thanks him for coming to see him when the rest of the people at the station didn’t even send a card.
