When Stan is chasing Roger they pass a giant photo of the lunar module and American flag on the moon, which Stan alluded to earlier when he said that the building everyone is in, is where they faked the moon landing.
When Stan was showing the Torture Bloopers, it mirrored what American censors consider acceptable for television. The blood, gore, and violence was fine, but showing sex is unacceptable.
The title is a reference to Phantom of the Opera, the longest-running Broadway musical.
