Becca wants to invite Rob Wetzel to a school dance, but she doesn't know if he likes her. So Kerry suggests that they create a ""Cool Book"" and pass it around so that others will write down what they think of everyone in school and then they'll know who's cool or not cool. Becca thinks it's a good idea at first but soon realizes that there are some things you'd rather not know. Meanwhile, Tucker agonizes over why no one has written anything about him in the cool book so he does it himself.
