Plot
When Doreen's friend, Betsy, brings over her newborn baby and takes away all of the attention from Stuart, Stuart becomes extremely jealous of the baby and does several things to get his mom and her friend's attention such as dancing around, drinking coffee and hammering the end table, as well as spitting up his Bundt cake to imitate the baby spitting up. Betsy resolves to fix the jealousy by having Stuart hold the baby and bond with him. While they go to find a camera to take a picture of Stuart and the baby, he fixates on a fire poker, the hammer and the cake cutter, implying murderous thoughts to kill the baby. However, it sneezes and Stuart becomes excited, saying "bless you" and smiling as his mom takes a picture of the two of them.
