Jay notices the attention Jr. is lavishing on Vanessa and decides that Michael's ignoring her. Meanwhile, Franklin decides he's too short, when he can't meet a roller coaster's height requirement.

Jay's psychology professor doesn't like her. Bad news, considering that the final's coming up. Also bad news is Michael's determination to be her "study buddy." Meanwhile, Kady fears that Franklin's interested in another girl, a fellow brainiac named Emerson (after Ralph Waldo).
