When Louie and Pamela enter the house, Pamela is wearing a green coat. When she turns around she's not wearing it anymore
Louie goes to view an apartment that it turns out had previously been owned by Lennie Bruce. He goes outside with the Realtor to the rear garden. While he is there he starts to turn around and around on the spot and the patio doors they came through go from being open to closed during the sequence several times.
