Goof: When Baby Mailbox brings young Steve the mail he is shown wearing the same flagwarmer that Steve did not give him until he grew up.
When Baby Mailbox is about to deliver the mail and the Mailbox song starts, Young Steve doesn't sing the familiar lyrics to the song; he just runs around the room and finally yells, "Maiiillll!"
In "Meet Joe," Joe said he made his duck doll, Boris, himself, but at the beginning of Mr. Salt's video, the camera zooms in on baby Joe, and there's Boris sitting right next to him. Does this mean Joe was some kind of prodigy tailor to be able to make a doll as a baby?
Joe: Mr. Salt, we were just babies. We don't remember what happened.
Steve: (reading from "About A Puppy") But what Blue wanted more than anything else was a friend to play with.
Joe: It's my brother Steve. He's calling all the way from college.
