Corrected entry: Joey stated his age as "55...ish" in the first episode, while Jesse says that Joey is 60. But in the season 2 episode "New Kids in the House", DJ is turning 39 years old. This means that Joey should be nearly 70. He was 29 or 30 when he first moved in with Danny, who turned 30 in the first season of the original show. It was established during the first show that Danny and Joey were in school together.
