"The Ghost of Suite 613" is the nineteenth episode of The Suite Life of Zack & Cody.
A rumor is circulating around the Tipton Hotel that Suite 613 is haunted by a ghost. Meanwhile, Zack plays practical jokes on everyone, embarrassing them around other people. Later, when they hear that London has dropped her purse with a thousand dollars in Suite 613, Maddie, London, Zack, and Cody all run up to get it. On the way, Muriel tells them about the ghost whose name was Irene. A very wealthy woman. In 1942 Irene and her husband checked in on their honeymoon night and then he went off to join the Allies in World War 2 and never came back. He "met" an Italian woman. Irene snapped and threw a gift of hers at the mirror thus shattering it and unintentionally killing herself. Muriel then leaves. When Mr. Moseby finds them in the suite later on, he tells them of the experience he had with suite 613 when he was only a bellhop in the hotel. Then Zack dares Cody to spend a night at 613 and the person who runs out first owes the other five dollars. In the suite, they try to talk to the spirit (Cody, Zack, London, Maddie, and Esteban) getting Esteban possessed and making Cody, Maddie and London disappear. It is then revealed to be a practical joke for Zack. At the end of the episode, Zack and Cody look for Cody's blanket when a woman who looks exactly like Irene approaches them and gives Cody back the blanket and leaves, passing through the wall with a portrait in the wall - meaning the ghost of Irene is very real.
- Irene, the ghost of suite 613, is mentioned in The Suite Life on Deck episode "The Ghost and Mr. Martin", when Zack says that ghosts exist because they saw one in the Tipton hotel. Orlando Bloom is also mentioned by London when they were having pizza.
