I Was Bitten (2008)

S1E9 A Dumb Wish

During an unexpected autumn cleaning, Billy discovers an ancient, cursed lamp hidden in Grim's trunk. Upon rubbing it, he inadvertently unleashes the curse Grim had cautioned them about—his own mother. Faced with three wishes, Billy squanders his first wish on wanting to know what to wish for. Annoyed, Mandy wishes for Billy and Grim to "be quiet," preventing Grim from making his wish. Ultimately, Mandy opts for her final wish to bring her the most happiness. She wishes for everyone in the world to disappear, much to her delight.
