This episode aired in the week following North America's largest Doctor Who convention, Gallifrey One. It's unknown if this was intentional. However, the second episode following was set on Thanksgiving, so it may just be a nice coincidence due to the delayed run of the season.
Chevy Chase's character, Pierce, refers to the Inspector Spacetime Convention as a "Captain Worf Convention." This is likely a reference to the iconic Star Trek Character, Worf, who premiered in the 2nd Star Trek series, The Next Generation. However, he never achieved the rank of Captain in any canonical Star Trek show or movie. He does however command a ship at the rank of Commander, the Defiant.
