The only Office episode directed by J.J. Abrams.
Michael attending magic camp was mentioned during A Benihana Christmas (2006). Dwight admits in his CIA application that he lied to cover for Michael who had claimed to be out sick but was actually at Magic Camp.
During his house inspection, Dwight sits in a rocking chair in a boy's room and states that he wants one, too. In later episodes (first time Money (2007)) you can see a chair just like that one on the porch at Schrute Farms.
When Michael yells, "I love this woman!," he is imitating a popular commercial for diamonds. In the ad, the woman is initially embarrassed but eventually hugs him and says, "I love this man." It is also possibly making fun of Tom Cruise when he was on Oprah announcing his love for Katie Holmes.
Stanley's daughter Melissa makes her second appearance in the series appearing in a deleted scene when she approaches Ryan asking if he remembers her. After that, Ryan is once again confronted by Stanley.
