James buys a motorcycle to impress Lucy, but he has no idea how to drive it. Meanwhile, Kendall gives Jo lessons in how to drive a stick shift; and Carlos and Logan are reluctant to give up a piece of childhood memorabilia.
The boys appear on a children's TV show, but the gig doesn't go smoothly thanks to Kendall's bad acting; Carlos' interest in the show's teen star; and Logan and James' fight with the "Yo Gabba Gabba!" characters.
In the fourth-season opener, the guys worry about competition from British boy bands. They think hiring a new music manager will help, but they clash over whom to hire, causing a schism within the band.
