Stu and Stewie's Excellent Adventure

Stewie's future self, Stu, is holidaying in the present by time travel. When Stu heads home, Stewie stows away and is passed off as a Nicaraguan boy called Pablo. He learns that at 35 he will be a virgin working at the Quahog Circuit Shack and living alone. Appalled, Stewie redecorates Stu's flat and engineers his first sexual encounter, with a colleague named Fran. She tells everyone, and Stu loses his job. Stu blames the day he nearly died at the pool, whose memory will resurface at twenty and leave him unable to take risks.
