Dana Carvey's impersonation of Mickey Rooney in the Celebrity Teen Crisis Center sketch is based on the period they worked together on the short lived sit-com One of the Boys (1982).
The pre-taped 'Deidra Wurtz: Downsizing Expert' sketch was filmed for the previous show, but not shown until this one. Jesse Eisenberg can be spotted as one of the employees during the office meeting scene.
