When Bob, Linda, Louise, and Gene discuss Tina getting detention, Gene is laying face down on his parents' bed kicking a pillow with his feet. The pillow underneath his feet temporarily vanishes but indentation marks continue to form at the end of his shoes as he kicks, as though the pillow were still there.
Linda: We need to go over some ground rules for tonight Miss Mouthy: no boys, no partying, no summoning spirits or switching bodies, and no filling the house with soap bubbles. You hear me, Tina?
Her erotic friend fiction is the best. I want to read all her erotic fiction about all the tv shows. The ending to this episode is superb. Also the hard rock song about Tammy making Tina shoplift ... so funny!
