The breastplate and mailed gloves Tim is wearing for his Halloween outfit are recycled props from Richard Gere's costume in "First Knight", which was released earlier the same year this episode aired.
The episode's title references the famous quote: "Let Them Eat Cake"
When Tim and Jill return home and crash the party, most of the kids can be seen leaving out the front door in the background, except for Lea Moreno's character Bridget. She can been seen looking back at the camera before turning and walking further into the house towards the stairs.
