Slater mentions the tranquilizer lasts 60 seconds - Krieger wakes up exactly 60 seconds after getting shot.
The carnivorous plant that tries to eat Ray is an homage to the plant in "Little Shop of Horrors".
When Krieger is showing Slater the cameras in the Tunt mansion, the computer screen behind him shows a YYZ logo on it. Another of the numerous references to Rush associated with Krieger's character.
When Lana comes down the stairs, Pam says, "Damn, Gina", a reference to Martin (1992), where Martin would say just that to Gina when he thought she looked particularly hot.
10 tranquilizer darts are shot.
