The episode begins in front of Springfield Elementary, as Mrs. Krabappel rounds up her class, including Bart, and prepares them for a field trip to the nuclear power plant. Otto, the bus driver, pulls up to the curb, and Bart chats with him outside of the bus, as the other kids find their seats. Mrs. Krabappel yells at Bart to get on the bus. When he scurries to find a seat, he is bummed to see the only one left is right next to Wendell, who is always queasy and pukes on every bus ride. As Otto takes the long way to the power plant, Bart struggles to behave on the bus ride. Mrs. Krabappel warns Bart that one more outburst will result in him singing to the class in the front of the bus. Sherri and Terri, who are sitting behind Bart, decide to get him in some more trouble. At the same time, they both kiss Bart on the cheek, causing him to yell out. Mrs. Krabappel makes good on her threat and forces Bart to sing in front of the class. The bus finally arrives at the power plant, and Bart congratulates Wendell for making the whole bus ride without puking, by slapping him on the back, which results in Wendell vomiting anyway.
Overall, a very emotional episode, but an okay/decent one.
