There is no opening theme song/credits sequence. The cast credits are played during the opening scene.
A picture of Roger Daltrey is visible on Jackie's bedroom wall when Kelso is painting her toenails. Daltrey played the uptight music teacher in the earlier episode, "That '70s Musical".
Although Eric and Michael have known each other since they were young, this is the first time Red and Kitty meet Casey Kelso.
The covers of two prominent magazines are seen in this episode. The issue of Cosmopolitan seen on the basement table, and later at the kitchen table, is the December 1977 issue, featuring Rene Russo on the cover. (The model's face is blurred in both scenes). In some scenes, Hyde's t-shirt features the April 1972 cover of Mad Magazine, featuring rows of "happy face" images.
In the scene where Kelso is painting the toenails of Jackie's right foot, her toenails should still be wet. But when she says they should look at Cosmo, Jackie is sitting on her right foot.
