Michelle and her class are going on a field trip to the local Museum of Natural History and Danny is one of the chaperones. When the other chaperone, Ms. Gwelch, cancels because of illness, he finds himself in over his head with being the only adult in charge of sixteen kids. Desperate to find a replacement before the trip, he persuades Jesse to come along. Danny feels hurt when Michelle chooses to be with Jesse's group instead of his, because she thinks that Jesse would let the kids have some fun, while Danny would act like a sergeant who makes too many rules.
