The intro scene, in which Mighty Mouse sips a cup of coffee and says, "How sweet it is", is imitating the old Jackie Gleason Show, in which Gleason began each episode doing the same thing.
The original broadcast version of this episode featured a live action clip at the very end - when Mighty Mouse is panicking over whether or not to actually marry Pearl, the scene suddenly cuts to a shot of animator Ed Bell sitting at his desk (at Bakshi Studios), having a similar meltdown and declaring "I can't do it! I can't marry him!" (the live action scene then cuts to a wide shot of his fellow Bakshi animators jeering and pelting him with wadded up animation paper)
